Description pknakal 2008-10-20 15:37:21 UTC 
I've reverse engineered web application with +/- 1300 classes. I've created a class diagram for some classes. When I try
to save the diagram the OutOfMemoryError (OOME) occur. So, I've shut down the IDE and start it again and ... the reverse
engineered model has gone. I've played a bit with storing and OOME and found this: The UML module stores the model like:
firstly remove the existing one and then try to store the new one, but when the OOME occur during the module storing,
the model file is lost forever. Is it possible as a first step backup the existing model, then save the updated one and
then remove the old one?

IDE memory setup is: -J-Xms128m -Xmx1024m

pknakal,
can you try to switch to Files tab in nb 6.1 and restore corrupted zero project file from local history?
Comment 7 Sergey Petrov 2008-10-23 13:24:48 UTC 
ok, I tried and it should work, I wasn't able to get oom, but I kill java process during saving then gotcorrupted
diagram file and was able to restore it from local history. the same should be for project files.
Comment 8 Viktor Lapitski 2008-10-23 16:51:14 UTC 
reverted backup fix back as local history already provides better solution
