Summary: Closing curly brace in literal string incorrectly
treated as expression terminator.
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Mac OS X 10.4
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
AssignedTo: [email protected]
ReportedBy: [email protected]
On tomcat 6.0.20 something like the following line in a JSP causes a exception:
<c:out value="${fn:trim('{world}')}"/>
After removing the closing curly brace from the literal ('{world}' -> '{world')
the JSP works. This behaviour seems specific to 6.0.20, as on 6.0.18 and 6.0.16
the line above works fine.
Example of exception:
=====================
org.apache.jasper.JasperException: An exception occurred processing JSP page
/test.jsp at line 11
8: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
9: </head>
10: <body>
11: <c:out value="${fn:trim('{world}')}"/>
12: </body>
13: </html>
