OgnlRuntime.getMethod fails to return correct method in some circumstances.
---------------------------------------------------------------------------
Key: OGNL-41
URL: https://issues.apache.org/jira/browse/OGNL-41
Project: OGNL
Issue Type: Bug
Reporter: Daniel Pitts
OgnlRuntime.getMethod fails to return correct method in some circumstances,
causing the wrong method to be called in "compiled" expressions.
The test case class is "Messages", which has a few "format" methods. When
attempting to call message.format("SomeString", one), OgnlRuntime.getMethod
returns null, instead of finding "format(String, Object)".
The problem is partially masked by the next call in ASTMethod:
"OgnlRuntime.getReadMethod", which returns the "format(String, Object[])"
method.
In the unit tests, MethodTest[3] is the one that is wrong. The expected result
should be "first", but is instead "foo".
When running MethodTest with compilation turned off, "foo" is return as
expected.
It looks like the logic in "getAppropriateMethod" is correct, but currently
relies on actual arguments, rather than just argument types. I think it could
be refactored and used for both the compiled and uncompiled use cases.
I have no patch at the moment.
