Vasily Zakharov commented on HARMONY-2615:
------------------------------------------
As HARMONY-2650 turned out to be not a bug, but a problem in org.mmtk.plan.Plan class, it
looks like some filter has to be added to this test to exclude classes that break the test
operation.
> [drlvm][test] Stress test for massive class loading from bootclasspath
> ----------------------------------------------------------------------
>
> Key: HARMONY-2615
> URL: http://issues.apache.org/jira/browse/HARMONY-2615
> Project: Harmony
> Issue Type: Test
> Components: DRLVM
> Reporter: Vasily Zakharov
> Attachments: CrashTestBCP.java

> This is a stress test which loads all the classes it finds in VM bootclasspath using
simple Class.forName() call.
>
> Not all of the classes are supposed to be loaded correctly this way, so the test ignores
any class loading errors - its main purpose is to make sure VM survives loading thousands
of classes without a crash. Also, investigating why particular classes fail to load may provide
clues to some other bugs in VM or classlib.
> I recommend including this test to some Harmony test suite that is run regularly, as
it may detect many VM issues that may occur in future.
> Currently this test crashes both on Windows/IA32 and Linux/IA32 in a very strange way
- at some point, unhandled exception occurs inside the catch(Throwable) block:
> 9879: org.mmtk.plan.Plan
> java.lang.ClassNotFoundException: null.Factory
> at java.lang.Class.forName(Unknown Source)
> at java.lang.Class.forName(Unknown Source)
> at org.mmtk.vm.VM.<clinit>(Unknown Source)
> at org.mmtk.utility.Constants.<clinit>(Unknown Source)
> at org.mmtk.plan.Plan.<clinit>(Unknown Source)
> at java.lang.VMClassRegistry.initializeClass(Native Method)
> at java.lang.Class.forName(Unknown Source)
> at java.lang.Class.forName(Unknown Source)
> at CrashTestBCP.load(CrashTestBCP.java:75)
> at CrashTestBCP.main(CrashTestBCP.java:98)
