[Bug libgcj/27908] VMSecureRandom generateSeed infinite loop? (Regression)

On futher inspection, it is pegging my CPU as well. `top' was lying to me.

It *looks* as though the test `while (running)' may have been optimized away,
because the threads continue to run even after the `running' variable has been
set to false.

The attached test case seems to illustrate the problem, and it looks like a GCJ
bug. This test case:

  - Fails to exit when compiled with GCJ 20060606. Command line: gcj -g -O2 -o
PR27908 
  - Fails to run interpreted when compiled with 'gcj -C'. Error is
'java.lang.IllegalAccessError: PR27908: PR27908$run1.stop()V'.
  - Fails to run on Sun Java 1.5.0_03 on GNU/Linux x86 if compiled with 'gcj
-C'. Error is 'java.lang.VerifyError: (class: PR27908, method: main signature:
([Ljava/lang/String;)V) Illegal use of nonvirtual function call'.
  - Fails to run on jamvm if compiled 'gcj -C'. Error is similar to that on
gij: an IllegalAccessError.

This test case runs fine if compiled with Sun's 'javac -source 1.4 -target 1.4'
on both gij, java, and jamvm.
