JCK test segmentation violation on solaris, also fails on win32

Test: vm/jni/ExceptionOccurred/exoc001/exoc00101/exoc00101.html
      exoc00101 - Determines if an exception is being thrown

To regress, see /usr/sqe/sqe_TestExec/jtpfiles/regress{bugNumber} for scripts to run solaris JCK.

Solaris result:
Failed. unexpected exit code

Per analysis/isolation of Dmitry Khukro:
"Throw" call breaks result of next "GetMethodID" call:

--exoc.java---------------------------------------------

package javasoft.sqe.tests.vm.exoc001.exoc00101;
import java.io.PrintStream;

public class exoc00101 {

  public static void main(String argv[])
  {
    exoc00101 tob = new exoc00101();
    Exception ex = new Exception();
    try {
      tob.exoc00101(ex, ex.getClass());
    } catch (Throwable e) {
    }
  }

  public native boolean exoc00101(Throwable ex, Class cl);

  static {
    try {
      System.loadLibrary("exoc");
    } catch ( UnsatisfiedLinkError e ) {
      System.loadLibrary("jckjni");

return JNI_FALSE;
 }
-----------------------------------------------------------------
Test outputs:

before Throw:
  mID != NULL
after Throw:
  mID == NULL

Call "CallBooleanMethod" with mID == NULL crashes VM:

segmentation violation
