[010628] To reproduce: 1. Convert filesystem into webmodule 2. Add some jar into WEB-INF/lib (not mandatory) 3. Create JSP in webmodule 4. Add this JSP to project (Tools | Add to Project) 5. Unmount webmodule 6. Click on filesystem node in explorer and select Customize from popup menu. Look what is happening. Now WEB-INF/classes and jars from WEB-IN/lib are repeatedly mounted and some are umnounted in infinitive loop, number of mounted filesystem increases and IDE loads 100% CPU. After a while tens of new filesystems are mounted.
I have seen looped mounting of WEB-INF/classes also without adding JSP to project.
The bug doesn't occur in build 010712_1.
