Comment 2 Marek Fukala 2007-02-06 11:54:47 UTC 
Looks like the problem is the same as in the Issue #94582 - the web module is
not properly parsed by jsp parser and thus it is throwing the exceptions. Can
you reproduce the problem/s on a brand new web project?
Comment 3 Marek Fukala 2007-02-16 15:39:56 UTC 
Martine, can you react to my last comment please?
Comment 4 Marek Fukala 2007-07-13 12:08:28 UTC 
Petre, can you please clarify the behaviour of the JSPParserAPI.getPageInfo()? Is that legal that it returns null under
some circumstances? Or is that a parser bug? Since you are the expert on the parser I would like to ask you to elaborate
how it should behave. Updating javadoc of the API would be superb.

I can remove the logged NPE from the JspSyntaxSupport.getImports() easily, but just in case that the null being returned
is valid in the testcase.
Comment 5 Marek Fukala 2007-10-12 18:42:10 UTC 
We need #109620 resolved first!
Comment 6 Marek Fukala 2008-08-22 12:05:02 UTC 
hopefully fixed + added more logging.
