Comment 2 Theofanis Oikonomou 2015-09-15 14:45:50 UTC

Most probably an invalid folder was selected to import settings from and user accepted that. Heap dump contains thousands of entries with file paths that are totally unrelated to netbeans options like "ProgramData/Application Data/...". Seems like a system junction file that actually points to itself was chosen? Anyway, fix from http://hg.netbeans.org/web-main/rev/d5d9a3c4e68f now stops asking user if he really wants to import options from what seems like an invalid folder and forbids doing that showing just an error. Thank you
