[Bug 56731] New: EL-Expression with escaped single quote leads to ELException

https://issues.apache.org/bugzilla/show_bug.cgi?id=56731

            Bug ID: 56731
           Summary: EL-Expression with escaped single quote leads to
                    ELException
           Product: Tomcat 7
           Version: 7.0.54
          Hardware: PC
            Status: NEW
          Severity: regression
          Priority: P2
         Component: Jasper
          Assignee: dev@tomcat.apache.org
          Reporter: c.luick@gmail.com

Error page with stack trace from tomcat

Hi Folks,

the following line in an 2.2-XML-JSP worked in Tomcat 7.0.39 but triggers an
ELException in Tomcat 7.0.54 (see attachment for details):

<div title="${empty myVar ? '\'in quotes\'' : ''}">test</div>

I seems that the expression "'\'test\''" leads to the the problem because
including it in parenthesis solves the problem in 7.0.54:

<div title="${empty myVar ? ('\'in quotes\'') : ''}">test</div>

The problem is that we have a lot of similar expressions containing escaped
single quotes in our webapp.

Thanks for your help,
Christof Luick.
