>From the stack trace, the cause of the failure seems to be that there is no ExecutionContext set on the Execution component [1]. On which request is this stack trace logged? Is it a GWT-RPC request? In this case the Execution is initialized by XWikiContextInitializationFilter [2] which calls ServletContainerInitializer#initializeRequest() where a new ExecutionContext is put on the Execution [3]. Otherwise, for an action request (save, preview, etc.) the ExecutionContext is initialized in XWikiAction [4].
If the ExecutionContext is properly initialized then it means some code removes it from the Execution afterwards. Putting some breakpoints in DefaultExecution [5] should catch this code.
