[jira] Commented: (XMLBEANS-206) Wrong method finding in getMethod() of InterfaceExtensionImpl
[ http://issues.apache.org/jira/browse/XMLBEANS-206?page=comments#action_12332653 ]
Lawrence Jones commented on XMLBEANS-206:
-----------------------------------------
Am attaching the stack trace you see for this error (with an interface with 2 same-named methods - one takes String, other takes String & int)
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2

> Wrong implementation of getMethod() in InterfaceExtensionImpl class could lead to ArrayIndexOutOfBoundsException.
> Old implementation :
> static JMethod getMethod(JClass cls, String name, JClass[] paramTypes)
> {
> JMethod[] methods = cls.getMethods();
> for (int i = 0; i < methods.length; i++)
> {
> JMethod method = methods[i];
> if (!name.equals(method.getSimpleName()))
> continue;
> JParameter[] mParams = method.getParameters();
> for (int j = 0; j < mParams.length; j++)
> {
> JParameter mParam = mParams[j];
> if (!mParam.getType().equals(paramTypes[j]))
> continue;
> }
> return method;
> }
> return null;
> }
> Correct impl-tion :
> static JMethod getMethod(JClass cls, String name, JClass[] paramTypes)
> {
> JMethod[] methods = cls.getMethods();
> for (int i = 0; i < methods.length; i++)
> {
> JMethod method = methods[i];
> if (!name.equals(method.getSimpleName()))
> continue;
> JParameter[] mParams = method.getParameters();
> // here was bug in possibe ArrayIndexOutOfBoundsException.
> // because methods could have same names but different
> // number of parameters
> if ( mParams.length != paramTypes.length ){
> continue;
> }
>
> for (int j = 0; j < mParams.length; j++)
> {
> JParameter mParam = mParams[j];
> if (!mParam.getType().equals(paramTypes[j]))
> continue;
> }
> return method;
> }
> return null;
> }
