| 95 NOTE about use of any ctor or function call that can trigger a safepoint/GC: | |
| 96 such ctors and calls MUST NOT come between an oop declaration/init and its | |
| 97 usage because if objects are move this may cause various memory stomps, bus | |
| 98 errors and segfaults. Here is a cookbook for causing so called "naked oop | |
| 99 failures": | |
| 100 | |
| 101 JVM_ENTRY(jobjectArray, JVM_GetClassDeclaredFields<etc> { | |
| 102 JVMWrapper("JVM_GetClassDeclaredFields"); | |
| 103 | |
| 104 // Object address to be held directly in mirror & not visible to GC | |
| 105 oop mirror = JNIHandles::resolve_non_null(ofClass); | |
| 106 | |
| 107 // If this ctor can hit a safepoint, moving objects around, then | |
| 108 ComplexConstructor foo; | |
| 109 | |
| 110 // Boom! mirror may point to JUNK instead of the intended object | |
| 111 (some dereference of mirror) | |
| 112 | |
| 113 // Here's another call that may block for GC, making mirror stale | |
| 114 MutexLocker ml(some_lock); | |
| 115 | |
| 116 // And here's an initializer that can result in a stale oop | |
| 117 // all in one step. | |
| 118 oop o = call_that_can_throw_exception(TRAPS); | |
| 119 | |
| 120 | |
| 121 The solution is to keep the oop declaration BELOW the ctor or function | |
| 122 call that might cause a GC, do another resolve to reassign the oop, or | |
| 123 consider use of a Handle instead of an oop so there is immunity from object | |
| 124 motion. But note that the "QUICK" entries below do not have a handlemark | |
| 125 and thus can only support use of handles passed in. | |
