Tried to get content assist in text pane of WPE, but after typing "<f:" and hitting Ctrl-Space got the following exception: java.lang.NullPointerException at

Hi Nitin, This looks like an issue with the JSP component. Can you help me triage this bug? -Raghu
This was experienced with fresh build (I-I200704190706) and fresh workspace. After closing Eclipse and then restarting, can no longer reproduce. Issue may be linked somehow to new workspace.
downgrading it to normal
Sure thing. *** This bug has been marked as a duplicate of bug 183243 ***
Closing.
