[testing] trying to run freemind with harmony
Hello:
I was trying to run Freemind under Windows XP Home Edition SP 2
using the latest harmony snapshot (August 4th). I have already run it in
Ubuntu Dapper, and it went fine, although freemind was not capable of
exporting to other formats (I think it is because javax.imageio package
is not implemented yet) Well, the question is that under Windows I get
an OutofMemoryError (no stack trace available) I have tried increasing
the heap size: java -Xmx512M -jar freemind.jar, but I still get the same
error message.

Re: [testing] trying to run freemind with harmony
Posted by Tim Ellison <t....@gmail.com>.
FYI : cannot reproduce on the classlib r432241 running on IBM VME
Windows XP. Freemind seems to work fine there[1].

Iñigo, the log above doesn't have any collection messages, thus
no collection had taken place, and the OutOfMemoryError is most likely
caused by some other reason -- not the java heap shortage.
I have just grepped DRLVM and found about 25 places where OOM is thrown
explicitly in the VM.
Applying following patch and running with '-verbose:oom -verbose:gc*'
may shed some light on the reason of the problem.

Have you tried -Xmx1g ? :)
The current GC implementation has several inefficiencies in handling objects
of size ~60 kb. In the worst case up to 53% of the heap can be wasted.
To get more information about heap usage, please add the command line argument
-verbose:gc*, and it will print a lot of information about its internal state.
Could you please send it to the list?
OutOfMemoryError can be caused by other reasons as well, e.g. shortage
of memory when creating new thread
(basically whenever VM developer decided that OutOfMemoryError was a right
thing to throw) -- this can be identified if the OutOfMemoryError was
thrown without any garbage collection logs before.

Thanks! Can you post a JIRA with the details?
I'm trying to get a new snapshot out today also, so look for that.
