Hello, Are there any plans to upgrade the version of Jackrabbit within the 2.6 release? The reason I ask is that we are in the final stages of development of a fairly CMS intensive application using 2.4. During our performance/load testing we ran into a number of serious threading issues (deadlocks and race conditions) as well as some memory leaks within the Jackrabbit 1.0 code. We posted some inquiries to the Jackrabbit user group and basically have been told that ?Jackrabbit 1.0 had several known serious bugs in this area. You should upgrade to 1.2.1.? For anyone interested, we were able to switch to Jackrabbit 1.2.1 fairly easily. All that was required was to change several import statements within HibernatePersistenceManager and minor edits to the build scripts. This change solved all of our threading and memory issues and improved our overall performance numbers.
