Lukasz Lenart commented on WW-3523:
-----------------------------------
I think this is the answer for your question:
// TODO: This is a hacky workaround until javassist supports
varargs method invocations
boolean varArgs = OgnlRuntime.isJdk15() && m.isVarArgs();
if (varArgs)
{
throw new UnsupportedCompilationException("Javassist does not
currently support varargs method calls");
}
> OGNL Varargs method invocation fails
> ------------------------------------
>
> Key: WW-3523
> URL: https://issues.apache.org/jira/browse/WW-3523
> Project: Struts 2
> Issue Type: Bug
> Components: Expression Language
> Affects Versions: 2.2.1
> Environment: Websphere 6.1
> Reporter: Alfredo Osorio
>
> I'm getting java.lang.IllegalArgumentException when trying to invoke a vararg
> method with OGNL.
> Here is an example of the method signature:
> public String sayHello(String... names);
> Expression used to invoke it
> sayHello('Alfred', 'John')
> assuming that the bean with the method has been pushed onto the ValueStack.
> I think it has something to do with:
> ognl.OgnlRuntime.callAppropriateMethod(...)
> and the arguments being sent to:
> invokeMethod(target, method, convertedArgs);
