Description Marek Fukala 2007-11-14 11:40:57 UTC 
1) open an html file
2) type: <!X -- comment --
3) type: >

-> the completion code invokes HTMLSyntaxParser which stays in an infinite loop:

"AWT-EventQueue-1" prio=1 tid=0x09305468 nid=0x4f10 runnable [0x834ad000..0x834ae140]
        at org.netbeans.editor.ext.html.HTMLSyntaxSupport.getElementChain(HTMLSyntaxSupport.java:490)
        at org.netbeans.editor.ext.html.HTMLSyntaxSupport.checkCompletion(HTMLSyntaxSupport.java:912)
        at org.netbeans.modules.editor.html.HTMLCompletionProvider.getAutoQueryTypes(HTMLCompletionProvider.java:80)
        at org.netbeans.modules.editor.completion.CompletionImpl.insertUpdate(CompletionImpl.java:284)
[snip]

The problem is a regression of lexerization of the html editor module done before a year. The same problem appears in
netbeans 6.0 M8 from March of this year. Since noone reported the issue during the year I do not consider it as a
stopper for Netbeans 6.0. The final decision in on QE though. 

BTW the errorneous code will be removed from trunk soon and replaced by new clean solution.

I agree the issue isn't stopper for NB 6.0.
Comment 2 Petr Jiricka 2007-11-15 12:48:57 UTC 
Setting target milestone to Dev.
Comment 3 Marek Fukala 2008-01-09 02:15:58 UTC 
I cannot reproduce the issue now, maybe fixed by some other fixes in the lexer. Jindro, could you please to verify that
the issue is not valid? Thanks,
Comment 4 Jindrich Sedek 2008-01-09 10:43:52 UTC 
I'm not able to reproduce any loop, seems to work fine.
