Subject [Lucene-java Wiki] Update of "SunJavaBugs" by MikeMcCandless
Date Wed, 01 Apr 2009 11:39:50 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-java Wiki" for change notification.

The following page has been changed by MikeMcCandless:

The comment on the change is:
Adding page describing known Sun Java bugs that affect Lucene

New page:
= Sun Java Bugs =

Sometimes Lucene runs amok of bugs in Sun's Java implementation.  In
certain cases we whittle it down to a small test case, open an issue
with Sun, and hopefully Sun fixes it.  In other cases we know the bug
is in the JRE but we haven't narrowed it enough to open a bug with
Sun.  Sometimes we can work out a simple workaround in Lucene.

We try to open a Lucene mirror bug to provide details on how Lucene is
affected, iterate on a compact test case for Sun, etc.

If you are affected by one of these issues that Sun has yet to accept
or resolve, or simply have some spare votes, please consider adding
your vote to the bug (on Sun's bug page):

|| Sun bug || Lucene mirror bug || Impact to Lucene || State, Priority || Workaround ||
|| [ 6265734] || [
LUCENE-573] || {{{NIOFSDirectory}}} has very poor performance on Windows || Accepted, Low
|| Use {{{FSDirectory}}} or {{{MMapDirectory}}} on Windows ||
|| [ 6478546] || [
LUCENE-1566] || You hit a false {{{OutOfMemoryException}}} when loading norms in an index
with many docs || Accepted, Low || Locally patch Lucene to load large contiguous byte sequences
in chunks ||
|| [ 6707044] || [
LUCENE-1282] || Index corruption || Fixed as of 1.6.0_10, High || Lucene code base has a workaround
in it ||
|| (No sun bug yet) || [ LUCENE-1342] ||
SEGV during indexing, with Java 1.6 64 bit || (No compact test case yet) || None known ||
