EL method signature inspection

Reports method calls in EL that don't match method-signature constraints in TLD files.

Example Java class:

public class ExampleAction { public void goodAction() { ... } public void badAction(String str) { ... } }

Example JSP file:

<jsp:useBean id="example" scope="request" type="org.example.ExampleAction"/> <f:view> <h:commandButton action="#{example.goodAction}"/> // Good: method accepts zero arguments and returns `void` <h:commandButton action="#{example.badAction}"/> // Error: method `void badAction(String)` returns `java.lang.String` type instead of `void` </f:view>
