User Comments:
GUEST: When doing formatted paste. IDE was in debug mode (Java web app). It was like dead-lock, so I killed Tomcat, which helped IDE to wake up again.

As can be seen from the attached snapshot, AWT EDT is blocked by
GsfReformatTask trying to acquire the parser lock while extremely slow ELHintsProvider task is in progress.

As far as I saw "JsfVariablesModel.getModel" recreates the JsfVariablesModel every time when it's called and doesn't use the cached value at all. :/ There is missing synchronization but it's quite risky to add it there now because of one report we have so far. Targeting to the Next.

Duplicate of issue #242541. Too many index accesses by getting composite components.
