/*
|
|
1980 |
The following section of code avoids a class loading problem
|
|
1981 |
with RMI. The problem is that an RMI stub, when deserializing
|
|
1982 |
a remote method return value or exception, will first of all
|
|
1983 |
consult the first non-bootstrap class loader it finds in the
|
|
1984 |
call stack. This can lead to behavior that is not portable
|
|
1985 |
between implementations of the JMX Remote API. Notably, an
|
|
1986 |
implementation on J2SE 1.4 will find the RMI stub's loader on
|
|
1987 |
the stack. But in J2SE 5, this stub is loaded by the
|
|
1988 |
bootstrap loader, so RMI will find the loader of the user code
|
|
1989 |
that called an MBeanServerConnection method.
|
|
1990 |
|
|
1991 |
To avoid this problem, we take advantage of what the RMI stub
|
|
1992 |
is doing internally. Each remote call will end up calling
|
|
1993 |
ref.invoke(...), where ref is the RemoteRef parameter given to
|
|
1994 |
the RMI stub's constructor. It is within this call that the
|
|
1995 |
deserialization will happen. So we fabricate our own RemoteRef
|
|
1996 |
that delegates everything to the "real" one but that is loaded
|
|
1997 |
by a class loader that knows no other classes. The class
|
|
1998 |
loader NoCallStackClassLoader does this: the RemoteRef is an
|
|
1999 |
instance of the class named by proxyRefClassName, which is
|
|
2000 |
fabricated by the class loader using byte code that is defined
|
|
2001 |
by the string below.
|
|
2002 |
|
|
2003 |
The call stack when the deserialization happens is thus this:
|
|
2004 |
MBeanServerConnection.getAttribute (or whatever)
|
|
2005 |
-> RMIConnectionImpl_Stub.getAttribute
|
|
2006 |
-> ProxyRef.invoke(...getAttribute...)
|
|
2007 |
-> UnicastRef.invoke(...getAttribute...)
|
|
2008 |
-> internal RMI stuff
|
|
2009 |
|
|
2010 |
Here UnicastRef is the RemoteRef created when the stub was
|
|
2011 |
deserialized (which is of some RMI internal class). It and the
|
|
2012 |
"internal RMI stuff" are loaded by the bootstrap loader, so are
|
|
2013 |
transparent to the stack search. The first non-bootstrap
|
|
2014 |
loader found is our ProxyRefLoader, as required.
|
|
2015 |
|
|
2016 |
In a future version of this code as integrated into J2SE 5,
|
|
2017 |
this workaround could be replaced by direct access to the
|
|
2018 |
internals of RMI. For now, we use the same code base for J2SE
|
|
2019 |
and for the standalone Reference Implementation.

/*
|
|
2133 |
The following code performs a similar trick for RMI/IIOP to the
|
|
2134 |
one described above for RMI/JRMP. Unlike JRMP, though, we
|
|
2135 |
can't easily insert an object between the RMIConnection stub
|
|
2136 |
and the RMI/IIOP deserialization code, as explained below.
|
|
2137 |
|
|
2138 |
A method in an RMI/IIOP stub does the following. It makes an
|
|
2139 |
org.omg.CORBA_2_3.portable.OutputStream for each request, and
|
|
2140 |
writes the parameters to it. Then it calls
|
|
2141 |
_invoke(OutputStream) which it inherits from CORBA's
|
|
2142 |
ObjectImpl. That returns an
|
|
2143 |
org.omg.CORBA_2_3.portable.InputStream. The return value is
|
|
2144 |
read from this InputStream. So the stack during
|
|
2145 |
deserialization looks like this:
|
|
2146 |
|
|
2147 |
MBeanServerConnection.getAttribute (or whatever)
|
|
2148 |
-> _RMIConnection_Stub.getAttribute
|
|
2149 |
-> Util.readAny (a CORBA method)
|
|
2150 |
-> InputStream.read_any
|
|
2151 |
-> internal CORBA stuff
|
|
2152 |
|
|
2153 |
What we would have *liked* to have done would be the same thing
|
|
2154 |
as for RMI/JRMP. We create a "ProxyDelegate" that is an
|
|
2155 |
org.omg.CORBA.portable.Delegate that simply forwards every
|
|
2156 |
operation to the real original Delegate from the RMIConnection
|
|
2157 |
stub, except that the InputStream returned by _invoke is
|
|
2158 |
wrapped by a "ProxyInputStream" that is loaded by our
|
|
2159 |
NoCallStackClassLoader.
|
|
2160 |
|
|
2161 |
Unfortunately, this doesn't work, at least with Sun's J2SE
|
|
2162 |
1.4.2, because the CORBA code is not designed to allow you to
|
|
2163 |
change Delegates arbitrarily. You get a ClassCastException
|
|
2164 |
from code that expects the Delegate to implement an internal
|
|
2165 |
interface.
|
|
2166 |
|
|
2167 |
So instead we do the following. We create a subclass of the
|
|
2168 |
stub that overrides the _invoke method so as to wrap the
|
|
2169 |
returned InputStream in a ProxyInputStream. We create a
|
|
2170 |
subclass of ProxyInputStream using the NoCallStackClassLoader
|
|
2171 |
and override its read_any and read_value(Class) methods.
|
|
2172 |
(These are the only methods called during deserialization of
|
|
2173 |
MBeanServerConnection return values.) We extract the Delegate
|
|
2174 |
from the original stub and insert it into our subclass stub,
|
|
2175 |
and away we go. The state of a stub consists solely of its
|
|
2176 |
Delegate.
|
|
2177 |
|
|
2178 |
We also need to catch ApplicationException, which will encode
|
|
2179 |
any exceptions declared in the throws clause of the called
|
|
2180 |
method. Its InputStream needs to be wrapped in a
|
|
2181 |
ProxyInputSteam too.
|
|
2182 |
|
|
2183 |
We override _releaseReply in the stub subclass so that it
|
|
2184 |
replaces a ProxyInputStream argument with the original
|
|
2185 |
InputStream. This avoids problems if the implementation of
|
|
2186 |
_releaseReply ends up casting this InputStream to an
|
|
2187 |
implementation-specific interface (which in Sun's J2SE 5 it
|
|
2188 |
does).
|
|
2189 |
|
|
2190 |
It is not strictly necessary for the stub subclass to be loaded
|
|
2191 |
by a NoCallStackClassLoader, since the call-stack search stops
|
|
2192 |
at the ProxyInputStream subclass. However, it is convenient
|
|
2193 |
for two reasons. One is that it means that the
|
|
2194 |
ProxyInputStream subclass can be accessed directly, without
|
|
2195 |
using reflection. The other is that it avoids build problems,
|
|
2196 |
since usually stubs are created after other classes are
|
|
2197 |
compiled, so we can't access them from this class without,
|
|
2198 |
again, using reflection.
