The latest version of jasper reports 0.6.6 does not contain the JRBshCompiler
compiler anymore - as per the release notes :

"the JRBshCompiler has been removed from the core library and provided
as a separate sample"

This breaks spring's compile-on-the-fly of jasper reports (java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/design/JRBshCompiler)

I searched on the boards and this doesn not seem to be a reported issue.
