I am also worried about the time it takes to run the CocoonBeanTestCase. We already run the unit tests all too seldom, and if they take a long time, nobody will ever want to run them more often. Ugo

This is necessary because the CocoonBeanTestCase loads "build/webapp/WEB-INF/cocoon.xconf", which contains references to components provided by blocks. This strikes me as a typical anti-pattern. What are we testing here? The CocoonBean or the components that it relies upon? If it's the latter, fine, but it's not a unit test anymore, it's an integration test and does not belong under the "junit-tests" target. If it's the former, it should be testable in isolation. In any case, it would be probably advisable to load the CocoonBean under test with a cocoon.xconf derived from a "no-blocks-included" configuration. This is all fair comment. Whilst I have a 'unit test' for the bean, in fact, the bean really depends upon the entirety of Cocoon, and is thus really more of a functional test. Given that some blocks have been known to break the bean, it is important that the test is run across the entire Cocoon. It is there somewhat more akin to an anteater test. Therefore, given these facts, I propose to leave the CocoonBeanTestCase disabled, and simply remove the test suite (as it isn't needed anyway.).

And many thanks to you for doing the work! I hope we soon will get rid of jisp. What about to deprecate current JISP support? If someone want to use JISP there is still a posibility using JCS.

I updated a server hosting a bunch of XSPs to current CVS. Using the default cocoon.xconf settings, first everything is fine, but after about an hour under medium load it is getting slower and slower and is starving while heap is growing to ~240M (-Xmx260m). can anybody confirm that these settings do work? /leo

Store: MUST hold NON Serializable objects, CAN persist Serializable objects on overflow (or any other reason), MUST persist all Serializable objects on shutdown.
