VM option '-ShowMessageBoxOnError'
VM option 'CompileThreshold=3'

TESTS FAILED :
All Javasoftsoft and Sunsoft fail when you run with
java -Xmixed -XX:CompileThreshold=3.
   or
java -Xcomp -XX:-ShowMessageBoxOnError

Try running Javasoft, Sunsoft test with

java_g -Xmixed -XX:CompileThreshold=3 then most of the tests PASS and few tests fail with the following OUTPUT message.
  or
java_g Xcomp -XX:ShowMessageBoxOnError

NOTE : Some of the failures gives error on
assert (idom == _root, "Control reaches root, but dominator does not");
 ....\domgraph.cpp, 489# ( BUG is already filed).

1. Install JDK FCS-O build.
2. Install Hotspot Beta1 Build C.
3. Run Javasoft, Sunsoft and Appletviewer tests.
