106 |
NOTE about use of any ctor or function call that can trigger a safepoint/GC: |
|
107 |
such ctors and calls MUST NOT come between an oop declaration/init and its |
|
108 |
usage because if objects are move this may cause various memory stomps, bus |
|
109 |
errors and segfaults. Here is a cookbook for causing so called "naked oop |
|
110 |
failures": |
|
111 |
||
112 |
JVM_ENTRY(jobjectArray, JVM_GetClassDeclaredFields<etc> { |
|
113 |
JVMWrapper("JVM_GetClassDeclaredFields"); |
|
114 |
||
115 |
// Object address to be held directly in mirror & not visible to GC |
|
116 |
oop mirror = JNIHandles::resolve_non_null(ofClass); |
|
117 |
||
118 |
// If this ctor can hit a safepoint, moving objects around, then |
|
119 |
ComplexConstructor foo; |
|
120 |
||
121 |
// Boom! mirror may point to JUNK instead of the intended object |
|
122 |
(some dereference of mirror) |
|
123 |
||
124 |
// Here's another call that may block for GC, making mirror stale |
|
125 |
MutexLocker ml(some_lock); |
|
126 |
||
127 |
// And here's an initializer that can result in a stale oop |
|
128 |
// all in one step. |
|
129 |
oop o = call_that_can_throw_exception(TRAPS); |
|
130 |
||
131 |
||
132 |
The solution is to keep the oop declaration BELOW the ctor or function |
|
133 |
call that might cause a GC, do another resolve to reassign the oop, or |
|
134 |
consider use of a Handle instead of an oop so there is immunity from object |
|
135 |
motion. But note that the "QUICK" entries below do not have a handlemark |
|
136 |
and thus can only support use of handles passed in. |
