Comment 3 Exceptions Reporter 2015-01-06 09:24:12 UTC 
This bug already has 10 duplicates 
see http://statistics.netbeans.org/exceptions/detail.do?id=212037
Comment 4 Tomas Stupka 2015-09-07 11:33:52 UTC 
all reports from 8.0.1 and 8.0.2, but no reports from dev 
quite probable that it was fixed in the mean time
closing for now
