Comment 2 Milos Kleint 2012-07-16 13:33:55 UTC 
most likely caused by general lack of free memory, the SoftReference holding MavenProject instance was freed and later on reloaded during the call in the stack

open projects hard-reference the MavenProject instance, so that it never gets released, it's required all the time anyway and is immediately recreated  after GC
Comment 4 Quality Engineering 2012-11-08 02:54:51 UTC 
Integrated into 'main-golden', will be available in build *201211080001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: #194908, #215352 when project is open, use hard reference to keep MavenProject always around, before it gets opened and after it gets closed, keep on using the SoftReference
