Description Smeers 2014-07-11 16:10:46 UTC 
Hello,

Whenever I try to open a project it starts the process "Background scanning of projects..."
Because it takes so long it crashes my Netbeans, but this time I got exceptions. Here are te exceptions I got all in once:

To investigate this problem we need the heap dump written when java.lang.OutOfMemoryError happened. This heap dump is NetBeans userdir <http://wiki.netbeans.org/FaqWhatIsUserdir> in <userdir>/var/log directory. Please zip it and upload it at <http://deadlock.netbeans.org/job/upload/build>. Thanks.
