DO NOT REPLY [Bug 51177] New: javax.el.MapELResolver getType returns
class of kept object instead of Object.class
https://issues.apache.org/bugzilla/show_bug.cgi?id=51177
Bug #: 51177
Summary: javax.el.MapELResolver getType returns class of kept
object instead of Object.class
Product: Tomcat 6
Version: 6.0.26
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Servlet & JSP API
AssignedTo: dev@tomcat.apache.org
ReportedBy: fedd@sql.ru
Classification: Unclassified
Created attachment 26977
--> https://issues.apache.org/bugzilla/attachment.cgi?id=26977
JSP script reproduces the bug. Uncomment lines 46, 47 to see the real problem.
Hello,
This is observed in Tomcat 6.0.26, Java 1.6 (Netbeans 6.9.1 bundle).
The MapELResolver getType method returns the class of the kept object instead
of Object.class. The Java specification says, "If the base object is a map,
[getType] returns the most general acceptable type for a value in this map",
which should mostly be Object.class.
This makes impossible, for example, 1) to set a String value to a map
expression, if previously that key was mapped to an Integer; 2) if we are
putting an Integer to the value which is currently the String, the Integer gets
coerced to the String (according to org.apache.el.parser.AstValue
implementation, see lines 153-157.)
The attached JSP script reproduces this bug.
I couldn't figure out whether it is connected with bug 44637 (seems that
request was reverse to mine).
Thanks!

ListELResolver.getType() has the same issue

Thanks for the test case. I am looking at this now.
As an aside, the test JSP is invalid. You can't use hm.int since int is not a
valid Java identifier (it is a reserved word). Tomcat 6 lets you get away with
this. Tomcat 7 doesn't (unless you explicitly disable the check). This doesn't
affect the validity of this bug report. Replacing "int" with "integer" allows
the JSP to execute.
