Bug#619814: Slow OO Base performance with high cpu load

[S. Ellenberger]

Package: sun-java6-bin
Version: 6.22-1
Severity: normal
Tags: squeeze

The update from sun-java-6-bin to 6.24-1~squeeze1 severly slows down OO base
performance.

Searching a string in an sql databse using java jre becomes a matter of
minutes, not seconds. I noticed unusually high CPU load while the search is
ongoing.

Quite a lot of complaints about this performance drop since mid-February can be
found in the official ooforum and in Ubuntu MM launchpad.

Solutions where to exchange java6 with a different version from the official
sun hp or from the ubuntu java ppa.

I can't mix squeeze with those packages, so I reverted to sun-java6-bin 6.22-1
using the debian snapshot server and confirmed the search performance is now
back to normal.

Putting sun-java6-bin 6.22-1 on aptitude hold only can be a short term
solution, I'll run into update problems sooner or later, if I keep it on hold
for too long.

Any comments and suggestitions what a squeeze user can do?

Thanks and regards

Stefan
