When "rethrowing" an exception, C2 compiled code fails to notify jvmpi about method exit.

Fails on all platforms with hopper.

How to reproduce on sparc:

With attached HelloWorld.class, run:

$JAVA_HOME/bin/java -client -Xbatch -Xcomp -Xrunhprof:cpu=old HelloWorld

results in

HPROF ERROR: thread local table NULL in method exit fc720
HPROF ERROR: thread local table NULL in method exit fc720
HPROF ERROR: thread local table NULL in method exit fd3e0
HPROF ERROR : stack underflow in method exit
HPROF ERROR : stack underflow in method exit

Compare with C2 run:

$JAVA_HOME/bin/java -server -Xbatch -Xcomp -Xrunhprof:cpu=old HelloWorld

HPROF ERROR: thread local table NULL in method exit fc720
HPROF ERROR: thread local table NULL in method exit fc720
HPROF ERROR: thread local table NULL in method exit fd3e0
HPROF ERROR : stack underflow in method exit
HPROF ERROR : stack underflow in method exit
HPROF ERROR: method on stack top != method exiting..
HPROF ERROR: method on stack top != method exiting..
HPROF ERROR: method on stack top != method exiting..
HPROF ERROR: method on stack top != method exiting..

The additional "stack top != method" errors are indicative of the failure.

Using:

+PrintCompilation
CompileOnly=java/lang/ClassLoader.findBootstrapClass0,java/lang/ClassLoader.findBootstrapClass
-Inline

narrows the problem greatly.
