Summary: Class cast exception in tagPlugin Set generated code
Product: Tomcat 7
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Jasper

Test case for "Set"
It uses "Class.cast" to convert an object to a given class in the code
generated by tagPlugin "Set".
It causes an exception when the value is primitive type,
Here is a sample,
Caused by: java.lang.ClassCastException: Cannot cast class java.lang.Integer to
int
at java.lang.Class.cast(Class.java:1711)
at
org.apache.jsp.WEB_002dINF.views.error_jsp._jspService(error_jsp.java:108)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:668)
at
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:432)
... 52 more
The correct way is to use "ELSupport.coerceToType".
Attached a patch and test case for this issue.
