Description Marek Fukala 2005-03-01 17:23:23 UTC 
[20050301]
To reproduce:
1) create a WP
2) copy attached file (select_java.jsp) into web
directory
3) include JSTL library into the WP
4) delete lines 44 and 45
5) put </c:if onto line 44 and invoke CC
=> the IDE consumes 100% of CPU until you close
the IDE.

Comment 3 Marek Fukala 2005-03-02 13:01:54 UTC 
fixed.

There was a problem with SyntaxElement.getPreviousElement() called on
sripting language syntax element. It returned itself what caused the
CC code to run in a neverending cycle.
