Hi,
since I installed the yourkit IDEA plugin I'm having a problem with IntelliJ and webapp support. I cannot tell you for sure that this is caused by the plugin but I never had this issue before I installed the plugin. I cannot reproduce it but perhaps someone else got this problem.
Occasionally when profiling a webapp (local Tomcat) IDEA will "forget" the package settings from the Webmodule (ie. where you tell it to copy *.lib to /WEB-INF/lib). It will just reset everything to "Do not package".
I can hardly believe that this has anything to do with yourkit but as I said it didn't happen before so I figured to post it here and see if someone else encounters this issue.
