Description
hprof aborts when run with classes using the new 292 features.

FWIW, option 2 (hprof) seems like a no-show on u2b08:

headius@headius-vbox-ubuntu:~/projects/redblack$
JAVA_HOME=~/jdk1.7.0_02/ ../jruby/bin/jruby -X+C
-J-Xrunhprof:cpu=times bm1.rb 20
HPROF ERROR: Unknown constant
[../../../src/share/demo/jvmti/java_crw_demo/java_crw_demo.c:693]
[hprof_init.c:210]
HPROF TERMINATED PROCESS

So I'm stuck with sampling.

This should reproduce with any jruby test or one of the 292 tests from mlvm or the JCK ones.  Here's a simple command line which will show at least one issue.
