StripesRuntimeException thrown in AnnotatedClassActionResolver when overriding
handler but returning a subclass of the original method
--------------------------------------------------------------------------------------------------------------------------------------
Key: STS-696
URL: http://www.stripesframework.org/jira/browse/STS-696
Project: Stripes
Issue Type: Bug
Components: ActionBean Dispatching
Affects Versions: Release 1.5.1, Release 1.5
Environment: Java 1.5.0_19
Reporter: Paul White
A net.sourceforge.stripes.exception.StripesRuntimeException is thrown in error
at:
net.sourceforge.stripes.controller.AnnotatedClassActionResolver.processMethods(AnnotatedClassActionResolver.java:226)
The exception message is "The ActionBean class <classname? declares multiple
event handlers for event '<eventname>'"
This occurs when processing methods for an actionBean that overrides a super
class handler with a method returning a subclass of the original method (eg
RedirectResolution overriding Resolution). The reason for the error is that
AnnotatedClassActionResolver.processMethods is not expecting
class.getDeclaredMethods() to include bridge methods. I will attach a test case
that displays the problem.
Workaround is to refactor subclasses to return Resolution rather than
ForwardResolution, RedirectResolution etc but it's valid in Java to override
methods this way so it should be supported ideally.
The solution is to change AnnotatedClassActionResolver.java, line 220 as
follows:
if ( Modifier.isPublic(method.getModifiers()) && !method.isBridge() ) {
