Do I understand correctly, that j.l.management support could be
implemented for DRLVM as follows:
1. Integrate HARMONY-1407 into classlib and obtain
UnsatisfiedLinkError on DRLVM.
2. Implement native methods in kernel classes as stubs returning some
realistic values. It could allow test and jconsole running.
3. Replace these stabs one by one with possible adding of the
interface functions in DRLVM modules like GC and TM.
Great. It's a good plan.
Really I have tried to go through this plan "ahead of time" :)
Currently I wrote native methods stubs and made run for the tests from
HARMONY-1407. The result is:
Tests run: 90, Failures: 15, Errors: 9
13 failures is StackTraceElement similar as Rui mentioned.
It's easy to fix.
8 errors due to not implemented method
at java.util.logging.LogManager.getLoggingMXBean(LogManager.java
:154)
It's easy to fix too. Just add one simple method to LogManager.
Other 3 problems needs additional investigation
Can you list out them?
I found that most native methods of this component are related with VM
platform, and some Java methods are called by native code(e.g. [1]) . Maybe
some of them are hard to replaced by simple stubs.
Is my activity helpful?
Ya, so helpful, I have more faith on this contribution now.
[1] MemoryMXBeanImpl.createMemoryManagerHelper(String name, int internalID,
boolean isGC)
Nathan, do you have similar or different plan for HARMONY-1407 integration?
Thanks,
Andrey
