2nd threadump
I must admit I do not know hot the lock happened. The EDT is blocked by JspKit$JspDeleteCharAction waiting for the document' write lock, while AnnotationHolder thread tries to acquire the DocumentView's PriorityMutex lock. Who has the PM locked I can't figure out. Milo, can you please take a look at the thread dump? Thank you. > while AnnotationHolder thread tries to acquire the DocumentView's

forgot to mention it tries to acquire the PM under the document's read lock, which blocks the EDT.
> Milo, can you please take a look at the thread dump? Thank you.
Same question as Marek - who owns the PriorityMutex?
Vlado, please run the IDE with
-J-Dorg.netbeans.lib.editor.util.PriorityMutex.level=FINEST
It should log who's the owning thread and the locking stacktrace.
Since it's a one year old issue I close as worksforme please reopen if necessary.

Created attachment 133132 [details] 1st threadump I simply selected text between <c:choose>...</c:choose> and IDE froze. I'm attaching 2 thread dumps taken in interval of approx 15 minutes. I can't reproduce it.
