This bug keeps coming back - after I get it once all Searches fail completely and the only way to "fix" it is to remove all Lucene files and force it to reindex the wiki - then some days later it happens again.

all of the quality checks we do for the primary one (DefaultURLConstructor). This is, for sure, a bug, and the right way to ferret it out is

I get it too, but completely randomly (it seems). Unfortunately, this is very hard to debug. Maybe it's some sort of a concurrency issue? Any Lucene experts around? Any new library versions? Workarounds?

I personally have never seen this problem, has anyone seen this problem occuring the last few months on the current JSPWiki releases ?

If nobody has seen it, well let us close the bug, and re-open it if the problem occurs.
