[jira] Created: (HARMONY-2833) [drlvm][jvmti] NULL pointer access
inside GetObjectClass() for exception object
[drlvm][jvmti] NULL pointer access inside GetObjectClass() for exception object
-------------------------------------------------------------------------------
Key: HARMONY-2833
URL: http://issues.apache.org/jira/browse/HARMONY-2833
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: Windows/ia32, Linux/ia32
Reporter: Ivan Popov
DRLVM (r489057) with JDWP agent crashed while debugging HelloWorld in Eclipse debugger.
The crash is because of NULL pointer access inside JVMTI function GetObjectClass(), which is invoked for exception object passed to Exception callback during classlib initialization (i.e., before main() is invoked).
Here is stack trace from VC++ debugger:
harmonyvm.dll!GetObjectClass(JNIEnv_External * jni_env=0x01173930, _jobject * obj=0x027773f0) Line 1088 C++

harmonyvm.dll!free(void * pBlock=0x41400000) Line 103 + 0x5 C
harmonyvm.dll!free(void * pBlock=) Line 103 + 0x5 C
To reproduce this crash:
1. Create DRLVM build and copy there jdwp and dt_socket libraries from jdktools build (or use federated build)
2. Start Eclipse and create HelloWorld project
3. Launch HelloWorld in debugger (Run->Debug)
4. Click Debug button and see crash
This crash does not occur if DRLVM is launched in -Xint mode.
