[Bug 56179] New: ParseException for EL expression "${((test ==
true))}"
https://issues.apache.org/bugzilla/show_bug.cgi?id=56179
Bug ID: 56179
Summary: ParseException for EL expression "${((test == true))}"
Product: Tomcat 8
Version: 8.0.3
Hardware: PC
OS: Mac OS X 10.4
Status: NEW
Severity: normal
Priority: P2
Component: EL
Assignee: dev@tomcat.apache.org
Reporter: holger.stenzhorn@gmail.com
I have the following JSP (test) file:
<html>
<body>
${((test == true))}
</body>
</html>
In Tomcat 7.0.52 this works fine but in Tomcat 8.0.3 the contained EL
expression throws the following ParseException:
org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for
servlet [jsp] in context with path [/test] threw exception [An exception
occurred processing JSP page /test.jsp at line 3
1: <html>
2: <body>
3: ${((test == true))}
4: </body>
5: </html>
Stacktrace:] with root cause
org.apache.el.parser.ParseException: Encountered " "==" "== "" at line 1,
column 10.
Was expecting one of:
")" ...
"," ...

Thanks for the report. The parser was getting confused by the unnecessary
brackets and thought it was looking at a lambda expression. I have updated the
parser to fix this and an additional related issue as well as adding some test
cases to confirm the fix.
The fix will be included in 8.0.4 onwards.
