Olivier Fambon commented on SEQUOIA-826:
----------------------------------------

Upgraded hsqldb.jar to 1.8.0.7 in the 2.10 branch.

The old version of hsqldb caused infinite loops upon vdb restart when using 
embeded hsqldb recovery log.

Sample use case:
- use embedded hsqldb recovery log (jdbc:hsqldb:file:)
- insert 7 blobs with size ranging form 1 to 7M
- shutdown vdb
- reload vdb <= hangs (100%CPU usage)

kill -QUIT shows controller had hsqldb thread looping at vdb load time.
Upgrading hsqldb.jar to 1.8.0.7 solves the issue.
