JEE5ModelProvider throws an IllegalStateException during a project rename scenario when files are open in editors. Seems the original project instance is no longer accessible in a call to load providers. Seems to happen with various editors open. One set of steps to repro... 1) Create a Dynamic Web Project just using default configurations 2) Open the web.xml with the default editor (XML editor) 3) Rename the project while the editor is open Result... !ENTRY org.eclipse.ui.navigator 4 2 2010-11-04 16:31:30.562 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.navigator". !STACK 0 java.lang.IllegalStateException:

Have also seen this exception during a project delete without having a file open in an editor.
Assigning to Kaloyan for initial investigation. My initial thought is that we need to have an additional check in JEE5ContentProvider.getCachedContentProvider() to see if the project is still accessible.
Dimitar, this is in your area of expertise.
Created attachment 182715 [details] fix for the IllegalStateException added check for accessible project in cache mechanism
Chuck can you review the fix.
