Comment 3 Tomas Danek 2008-09-01 12:37:05 UTC

have tried in 200809010201 and cannot reproduce ... any reason why is this not marked as fixed (will it be tested by
some regression tests, or is it waiting on some more robust fix, or do you still expect comments;), or...?)

Comment 4 Jan Lahoda 2008-09-10 17:05:00 UTC

The bug was waiting for more appropriate fix:
http://hg.netbeans.org/main?cmd=changeset;node=5b11c38cbf7d

The main difference is that if a fatal failure occurs during source root scan, the source root will be rescanned on next
start.

Comment 5 Quality Engineering 2008-09-11 17:39:47 UTC

Integrated into 'main-golden', will be available in build *200809111401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main/rev/5b11c38cbf7d
User: Jan Lahoda <jlahoda@netbeans.org>
Log: #145404: ensure that the source root is marked dirty when the old and new digests do not match, to guarantee recovery from a fatal failure.

Comment 6 Tomas Danek 2008-10-16 13:56:53 UTC
