This is solved in such a way that when JNI_CreateJavaVM is called it runs in pthread thus enabling the creation of jvm.

Sorry, had not noticed this before: We need error handling for the pthread routines. At the very least for pthread_create, which is the most likely to fail. Printing the errno and exiting with -1 should be fine in all cases. Would save the future analyzer of failed tests a lot of time.
