Description Patric Rufflar CLA 2006-05-31 20:09:03 EDT 
Hello everyone,

the following problem occours on WTP 1.5 RC4:

1. create a new jsp
2. paste the following:
<% 
String bla = "%>";

<b>As you can see, this is wrongly recognized as a html section

The parser marks line 2 as an error but this code seems correct.

Best Regards,
Patric Rufflar

I'll admit, I didn't look up the spec right now, but I do believe that 
the '%>' is supposed to be taken as the matching end of previous '<%'. 
And that if you really wanted '%>' in the string, you'd have to escape them. 

Please re-open if you can point me that part of the JSP spec which would prove me wrong.

Running it through Tomcat, I get this error:

This is part of a mass update to close out all stale WTP bugs which are in the resolved state without an appropriate targeted version.  If you feel this bug was closed inappropriately, please reopen.
