Testcase for 6173515 (Test6173515.sh) tests that exceptions are thrown when filling the heap and, separately, filling the perm generation by continually loading classes.

The ConsumePermGen test crashes on ia64: (although the testcase wrapper hides the crash and appears to pass)

hpzx:~/kevin/6173515 # $TESTJAVA/bin/java -noclassgc -XX:MaxPermSize=32m ConsumePermGen

Use of -noclassgc is perhaps asking for a problem when we need to load a class in order to proceed, and the perm space is absolutely full.

We need to load some classes after the exception happens:

java.lang.StackTraceElement
java.lang.Shutdown
java.lang.Shutdown$Lock
