WebFrameworkProvider.isInWebModule is called from the EDT. The whole method call initFrameworksList() should be done outside of EDT and the results should be saved per project, so it won't be called when opening the customizer once again. Similar situation was already fixed some time ago for Ant based projects.. see changeset: http://hg.netbeans.org/main-golden/rev/1bda3d0ec086
Fixed in: web-main #3f4982704bbb
Integrated into 'main-golden', will be available in build *201211020001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/3f4982704bbb User: Martin Janicek <mjanicek@netbeans.org> Log: #215047 - LowPerformance took 4124 ms.
