30s in java.io.File.listFiles() in other than AWT thread seems to slow down a single query to File.canRead in AWT thread. Either the system is too slow or overloaded. I really don't know what to do with this. Closing as won't fix.

Comment 3 Egor Ushakov 2012-10-31 16:36:18 UTC

please look through the latest reports, they seem to have been matched incorrectly, several are for bug 218234 for sure

Comment 4 Alexander Simon 2013-01-29 10:22:44 UTC

Slow file system is not justification of IO activity in EDT.
49 reports => P2

Comment 5 Jaroslav Havlin 2015-10-29 13:25:00 UTC

The last report comes from version 7.3 Beta.
It seems that the bug has been already fixed.
Closing the issue.
