Hi all,
I'm in the process of porting my embedded v8 from a very old version to
current stable. I have this code that is called from JNI from a different
thread than the one that initially created the Isolate and the initial
context:
v8::Locker l (isolate);
Isolate::Scope isolateScope(isolate);
Context::Scope
context_scope(*reinterpret_cast<Local<Context>*>(context->_context));
HandleScope scope (isolate);
TryCatch trycatch;
// Get pointers to persistent objects created by 'new Persistent<T>(_local)'
WrapPersistentObj* wo = (WrapPersistentObj*)thisPtr;
Local<Object> thisObj = (*reinterpret_cast<Local<Object>*>(&wo->obj));
WrapPersistentFunc* ws = (WrapPersistentFunc*)jsCbPtr;
Local<Function> callbackP = Local<Function>::New(isolate,
*reinterpret_cast<Local<Function>*>(&ws->callbackFunc));
int argcount = 0;
Handle<Value> argarray[] = { };
Handle<Value> result = callbackP->Call(thisObj, argcount, argarray);
The Call method crashes with this message in debug build (doesn't crash in
release build):

All access to the Isolate in all parts of the app is protected by Locker
instances, so I'm not sure where this comes from.
Any help would be appreciated.
Thanks and best,
Kevin
