<DD>If a String literal is specified as the expression, returns the 
 String literal coerced to the expected return type of the method 
 signature. An <code>ELException</code> is thrown if 
 <code>expectedReturnType</code> is void or if the coercion of the String literal 
 to the <code>expectedReturnType</code> yields an error (see Section "1.18 Type
 Conversion" of the EL specification).
 
 If not a String literal, evaluates the expression 
 relative to the provided context, invokes the method that was 
 found using the supplied parameters, and returns the result of 
 the method invocation.

 Any parameters passed to this method is ignored if isLiteralText()
 is true.
