Alexey Varlamov commented on HARMONY-5822:
------------------------------------------
To fix this:
1) the vm_register_jit_recompiled_method_callback() API must be extended to take 1 more parameter,
a caller method;
2) vmcore must de-register callbacks for each caller method when unloading their classloader.
> [drlvm][vmcore] class unloading does not clean JIT recompilation callbacks

> Key: HARMONY-5822
> URL: https://issues.apache.org/jira/browse/HARMONY-5822
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Affects Versions: 5.0M6
> Reporter: Alexey Varlamov
>
> There is a facility in DRLVM for notifying JIT of method recompilation, see vm_register_jit_recompiled_method_callback(JIT_Handle
jit, Method_Handle method, void *callback_data).
> Jitrino uses this feature to patch direct calls to methods (within other compiled methods)
upon recompilation of a callee method.
> However, in case then a caller method is unloaded, corresponding callbacks are not removed
and lead to SIGSEGV if a callee method is recompiled.
