I built tomcat from trunk (rev 1523639) and I'm having the same issue I had with glassfish EL implementation when using overloaded methods:
javax.el.ELException: Cannot convert ./ of type class java.lang.String to class java.net.URI at org.apache.el.lang.ELSupport.coerceToType(ELSupport.java:482) at org.apache.el.ExpressionFactoryImpl.coerceToType(ExpressionFactoryImpl.java:48) at javax.el.ELContext.convertToType(ELContext.java:473) at org.apache.el.lang.EvaluationContext.convertToType(EvaluationContext.java:155) at javax.el.ELUtil.invokeConstructor(ELUtil.java:261) at javax.el.StaticFieldELResolver.invoke(StaticFieldELResolver.java:203) at javax.el.CompositeELResolver.invoke(CompositeELResolver.java:256) at org.apache.el.parser.AstFunction.getValue(AstFunction.java:138) at org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:188) at javax.el.ELProcessor.getValue(ELProcessor.java:129) at javax.el.ELProcessor.eval(ELProcessor.java:115) at org.apache.naming.factory.ExpressionFactoryTest.elImplementationShouldWork(ExpressionFactoryTest.java:43) So I guess it's normal behaviour, isn't it? I don't think EL spec does mandate implementations to make their best effort to find a suitable method when invoking overloaded methods.
