Description Jaroslav Tulach 2010-11-28 08:02:16 UTC 
The usage of mmapped file buffer is probably causing failures on Linux machines without tweaked open file limit. I've seen the failure locally, now it also fails on 
http://deadlock.netbeans.org/hudson/job/ergonomics/1735/testReport/junit/org.netbeans.modules.apisupport.project.layers/LayerUtilsTest/testSystemFilesystemStandaloneProject/
The test needs to be rewritten to pass in all environment or excluded from the unit test validaton.
