holding write lock for way too long when reformatting code in org.netbeans.modules.css.editor.indent.CssIndentTask.reindent()	99.86448	42,919 ms (99.9%)	42,919 ms
Comment 4 David Konecny 2013-06-04 23:31:27 UTC 
We've had this problem in the past and at that time it boiled down to editor being slow in applying indent changes. In attached snaphost 40seconds are spent in the lexer.
Comment 5 Miloslav Metelka 2013-09-02 08:08:56 UTC 
We need to implement turning off of the lexer's token hierarchy during reformat to fix this.
