Geir, all,
I did reserched this failure some time ago. The same failure was observed on
gc.Finalizers.
Here is what I've found.
Now what is happening:
1) FinalizerThread is being run
2) java/lang/Object.notify()V is being compiled
3) java/lang/InternalError is being resolved (and loaded) for
java/lang/Object
4) GC happens while creating instance of java/lang/Class for
java/lang/InternalError
5) vm_hint_finalize happens
6) java/lang/ref/ReferenceQueue.enqueue is being called
7) java/lang/Object.notify()V is being compiled
8) java/lang/InternalError is being resolved (and loaded) for
java/lang/Object
9) ClassCircularityError occurs for java/lang/InternalError
10) VM returns to step (3)
11) Assertion happens in SuccessLoadingClass for java/lang/InternalError
as LoadingClass instance for this class was removed on step (9)
It can be tried to fix it in class loading, but I can imagine only one
generic solution for this problem: do not run Java while compiling.
Which more specifically means no Java heap allocations as our finalization
subsystem is partially written in Java.
Whole native stack on Windows look the following way:
