Description
CTW runs for appserver.jar and jck13classes.jar fail on Sparc and possibly other platforms.

For example,

java -server -Xss4m -verify -XX:-ShowMessageBoxOnError -XX:+CompileTheWorld -XX:CompileTheWorldStartAt=1 -Xbootclasspath/p:/net/vmsqe.sfbay/export/backup/testbase/CompileTheWorld/jarfiles/appserver.jar

causes a SEGV.
