The C main program of a particular JNI application calls
JNI_GetCreatedJavaVMs before calling JNI_CreateJavaVM .
The JNI_GetCreatedJavaVMs fails with SEGV due to the JNIWrapper
executing in an uninitialized VM . The stack is
  [1] ThreadLocalStorage::get_thread_via_cache(0x1515d8, 0xfc3b4ec0, 0x64, 0xfce0b, 0xfc36a16c, 0xfce0b5a4), at 0xfbc50784
  [2] GenericGrowableArray::GenericGrowableArray(0x151c98, 0x1515d8, 0xfc0b2fd8, 0x190, 0xfc36a16c, 0x0), at 0xfb9bf9cc
  [3] Histogram::Histogram(0x151c98, 0xfc103db4, 0x64, 0xd27f0, 0x0, 0x0), at 0xfb9c3530
=>[4] JNIHistogramElement::JNIHistogramElement(this = 0xd27b0, elementName = 0xfc1162fc "GetCreatedJavaVMs"), line 106 in "jni.cpp"
  [5] JNI_GetCreatedJavaVMs(vm_buf = 0xfce0b7e4, bufLen = 1, numVMs = 0xfce0b7e8),
 line 2063 in "jni.cpp"

The simplest fix is to just comment out the JNIWrapper in
JNI_GetCreatedJavaVMs . Otherwise some more logic is required
in JNIWrapper for the debug builds, to detect the "uninitialized VM"
  state.
