Description
Please upgrade Spring from 2.5.4 to 2.5.5. I generally think it's better to upgrade, but in this case, it's related to Hessian: In Spring 2.5.4, there's an issue related Hessian, which will set Hessian into debug mode. This is not a problem, but the remoting plugin is bundled with Hessian 3.1.1, which doesn't include the HessianDebugOutputstream classes.
Upgrading to 2.5.5 will fix this behaviour, as will upgrading the Hessian libraries to 3.1.6.
See: http://jira.springframework.org/browse/SPR-4208 for more information.
Attached is a test project which has been upgraded to version 3.1.6, and doesn't have the classnotfound problem, but it also includes 3.1.1, which, if enabled, does throw the class not found exception.
I have committed the Spring 2.5.5 JAR and all the tests are passing.
