             Summary: @Operation usage leads to java.lang.VerifyError 
                 Key: TAP5-2421
                 URL: https://issues.apache.org/jira/browse/TAP5-2421
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.4
            Reporter: Jochen Kemnade


I have annotated a method in a page class with {{@Operation}}. When the method is called, a {{VerifyError}} is thrown:
{code}
2014-11-24 13:19:46,685 [ajp-nio-9209-exec-33] ERROR o.a.t.m.T.RequestExceptionHandler - Processing of request failed with uncaught exception: java.lang.VerifyError: (class: pages/PageName$Invocation_methodName_1d10f8d1d549bc, method: proceedToAdvisedMethod signature: ()V) Incompatible argument to function
{code}.
The problem occurs with Java 7 as well as with Java 8 and regardless of whether the operation description contains a {{%}} or not.
Unfortunately, I cannot reproduce the problem on a different machine.
If I use {{OperationTracker}} "manually", no {{VerifyError}} is thrown.
The advised method throws multiple checked exceptions and an {{Error}}.
I'm not entirely sure what the error means, but I assume, the {{proceedToAdvisedMethod}} method is invoked with parameters, so it might be an issue with plastic rather than with tapestry-core.
