Description Jerome Lanneluc CLA 2002-05-04 11:49:34 EDT 
Build 20020502+

For info, I found the following in the console. This had no consequence as I 
was still able to do search query.

No luck trying to reproduce so far... I've tried changing the installed JRE & 
replaced jdt.core with every version in the repository... I've saved the 
workspace afterwards but nothing seems to trigger the walkback yet.

Version: 2.1

I was getting a similar error being logged every 12-13 seconds in my log, but 
with a different stack trace:

This was also reported on the eclipse-dev mailing list over the holidays.  The
user was on M4, and the stack trace was:

Comment 15 Philipe Mulet CLA 2003-01-28 10:10:30 EST 
Current behavior is acceptable (with crash recovery). Rewrite of the indexing 
infrastructure will occur for 2.2
Comment 16 Philipe Mulet CLA 2004-06-24 05:55:43 EDT 
Index infrastructure got rewritten for 3.0. Still a few cases seem to occur 
where crash recovery is required, but far less than with previous 
implementation.
Comment 17 Philipe Mulet CLA 2004-06-24 05:59:37 EDT 
reopen
Comment 18 Philipe Mulet CLA 2004-06-24 06:00:49 EDT 
Closing since new infrastructure got implemented.
Subsequent issues are to be logged in new defects (such as bug 68189).
