- // thread T1 in the fast unlock path, resulting in a missed wakeup for T2.
- // More precisely T1 in the stack-lock unlock path could "stomp" the
- // inflated mark value M installed by T2, resulting in an orphan
- // object monitor M and T2 becoming stranded. We can remedy that situation
- // by having T2 periodically poll the object's mark word using timed wait
- // operations. If T2 discovers that a stomp has occurred it vacates
- // the monitor M and wakes any other threads stranded on the now-orphan M.
- // In addition the monitor scavenger, which performs deflation,
- // would also need to check for orpan monitors and stranded threads.
- //
- // Finally, inflation is also used when T2 needs to assign a hashCode
- // to O and O is stack-locked by T1. The "stomp" race could cause
- // an assigned hashCode value to be lost. We can avoid that condition
- // and provide the necessary hashCode stability invariants by ensuring
- // that hashCode generation is idempotent between copying GCs.
- // For example we could compute the hashCode of an object O as
- // O's heap address XOR some high quality RNG value that is refreshed
- // at GC-time. The monitor scavenger would install the hashCode
- // found in any orphan monitors. Again, the mechanism admits a
- // lost-update "stomp" WAW race but detects and recovers as needed.

-// because a single patchable "set" instruction (NativeMovConstReg,
-// or NativeMovConstPatching for compiler1) instruction
-// serves to set up either quantity, depending on whether the compiled
-// call site is an inline cache or is megamorphic. See the function
-// CompiledIC::set_to_megamorphic.
-//
-// If a inline cache targets an interpreted method, then the
-// G5 register will be used twice during the call. First,
-// the call site will be patched to load a compiledICHolder
-// into G5. (This is an ordered pair of ic_klass, method.)
-// The c2i adapter will first check the ic_klass, then load
-// G5_method with the method part of the pair just before
-// jumping into the interpreter.
-//
-// Note that G5_method is only the method-self for the interpreter,
-// and is logically unrelated to G5_megamorphic_method.
-//
-// Invariants on G2_thread (the JavaThread pointer):
-// - it should not be used for any other purpose anywhere
-// - it must be re-initialized by StubRoutines::call_stub()
-// - it must be preserved around every use of call_VM
-
-// We can consider using g2/g3/g4 to cache more values than the
-// JavaThread, such as the card-marking base or perhaps pointers into
-// Eden. It's something of a waste to use them as scratch temporaries,
-// since they are not supposed to be volatile. (Of course, if we find
-// that Java doesn't benefit from application globals, then we can just
-// use them as ordinary temporaries.)
-//
-// Since g1 and g5 (and/or g6) are the volatile (caller-save) registers,
-// it makes sense to use them routinely for procedure linkage,
-// whenever the On registers are not applicable. Examples: G5_method,
-// G5_inline_cache_klass, and a double handful of miscellaneous compiler
-// stubs. This means that compiler stubs, etc., should be kept to a
-// maximum of two or three G-register arguments.

+ // thread T1 in the fast unlock path, resulting in a missed wakeup for T2.
+ // More precisely T1 in the stack-lock unlock path could "stomp" the

+ // an assigned hashCode value to be lost. We can avoid that condition
+ // and provide the necessary hashCode stability invariants by ensuring
+ // that hashCode generation is idempotent between copying GCs.
+ // For example we could compute the hashCode of an object O as
+ // O's heap address XOR some high quality RNG value that is refreshed
+ // at GC-time. The monitor scavenger would install the hashCode
+ // found in any orphan monitors. Again, the mechanism admits a

+3. MIME Header Fields
+
+ MIME defines a number of new RFC 822 header fields that are used to
+ describe the content of a MIME entity. These header fields occur in
+ at least two contexts:
+
+ (1) As part of a regular RFC 822 message header.
+
+ (2) In a MIME body part header within a multipart
+ construct.
+
+ The formal definition of these header fields is as follows:
+
+ MIME-message-headers := entity-headers
+ fields
+ version CRLF
+ ; The ordering of the header
+ ; fields implied by this BNF
+ ; definition should be ignored.
+
+ MIME-part-headers := entity-headers
+ [ fields ]
+ ; Any field not beginning with
+ ; "content-" can have no defined
+ ; meaning and may be ignored.
+ ; The ordering of the header
+ ; fields implied by this BNF
+ ; definition should be ignored.
+
+ The syntax of the various specific MIME header fields will be
+ described in the following sections.
+
+Freed & Borenstein Standards Track [Page 11]
+RFC 2045 Internet Message Bodies November 1996
+
+5.1. Syntax of the Content-Type Header Field
+
+ In the Augmented BNF notation of RFC 822, a Content-Type header field
+ value is defined as follows:
+
+ content := "Content-Type" ":" type "/" subtype
+ *(";" parameter)
+ ; Matching of media type and subtype
+ ; is ALWAYS case-insensitive.
+
+ type := discrete-type / composite-type
+
+ discrete-type := "text" / "image" / "audio" / "video" /
+ "application" / extension-token
+
+ composite-type := "message" / "multipart" / extension-token
+
+ extension-token := ietf-token / x-token
+
+ ietf-token := <An extension token defined by a
+ standards-track RFC and registered
+ with IANA.>
+
+ x-token := <The two characters "X-" or "x-" followed, with
+ no intervening white space, by any token>
+
+ subtype := extension-token / iana-token
+
+ iana-token := <A publicly-defined extension token. Tokens
+ of this form must be registered with IANA
+ as specified in RFC 2048.>
+
+ parameter := attribute "=" value
+
+ attribute := token
+ ; Matching of attributes
+ ; is ALWAYS case-insensitive.
+
+ value := token / quoted-string
+
+ token := 1*<any (US-ASCII) CHAR except SPACE, CTLs,
+ or tspecials>
+
+ tspecials := "(" / ")" / "<" / ">" / "@" /
+ "," / ";" / ":" / "\" / <">
+ "/" / "[" / "]" / "?" / "="
+ ; Must be in quoted-string,
+ ; to use within parameter values
+
+ description := "Content-Description" ":" *text
+
+ encoding := "Content-Transfer-Encoding" ":" mechanism
+
+ entity-headers := [ content CRLF ]
+ [ encoding CRLF ]
+ [ id CRLF ]
+ [ description CRLF ]
+ *( MIME-extension-field CRLF )
+
+ hex-octet := "=" 2(DIGIT / "A" / "B" / "C" / "D" / "E" / "F")
+ ; Octet must be used for characters > 127, =,
+ ; SPACEs or TABs at the ends of lines, and is
+ ; recommended for any character not listed in
+ ; RFC 2049 as "mail-safe".
+
+RFC 2045 Internet Message Bodies November 1996
+
+ must be used. An equal sign as the last character on a
+ encoded line indicates such a non-significant ("soft")
+ line break in the encoded text.
+
+ Thus if the "raw" form of the line is a single unencoded line that
+ says:
+
+ Now's the time for all folk to come to the aid of their country.
+
+ This can be represented, in the Quoted-Printable encoding, as:
+
+ Now's the time =
+ for all folk to come=
+ to the aid of their country.
+
+ Since the hyphen character ("-") may be represented as itself in the
+ Quoted-Printable encoding, care must be taken, when encapsulating a
+ quoted-printable encoded body inside one or more multipart entities,
+ to ensure that the boundary delimiter does not appear anywhere in the
+ encoded body. (A good strategy is to choose a boundary that includes
+ a character sequence such as "=_" which can never appear in a
+ quoted-printable body. See the definition of multipart messages in
+ RFC 2046.)

+===============================================================
+
+This test is about non-ASCII password input compatibility between
+JDK 5.0 and later versions. Before running the test, make sure that --
+
+ \$J5 points to a JDK 5.0 installation
+ \$JM points to the current installation
+
+The password string used in this test is $PASSW. If you find difficulty
+entering it in in your system, feel free to change it to something else
+by providing \$ALT_PASS. It should be no less than 6 characters and include
+some non-ASCII characters.
+
+For each test, type into the characters as described in the test header.
+<R> means the RETURN (or ENTER key). Please wait for a little while
+after <R> is pressed each time.
+
+\$J5 is now $J5
+\$JM is now $JM
