           Summary: IntrospectionUtils caches application classes
           Product: Tomcat 5
           Version: 5.5.9
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: magnus.alvestad@gmail.com


The class org.apache.tomcat.util.IntrospectionUtils caches the methods of 
classes used as parameters to the findMethods() method.  This cache has hard 
references, so when used against an application class (often an exception), the 
classloader of that application will never be unloaded.

Notice that changing the cache to a WeakHashMap would not help, as the class 
reference is also inside the Method object stored in the value field.

I think the same class (IntrospectionUtils) exists in the commons-modeler 
library, with the same problem.
