EL does not coerce String to Integer in equals operation in EAP 7

Solution Unverified - Updated -

Issue

EAP 7's EL equals operations work differently from EAP 6 one. EL does not coerce String to Integer in equals operation in EAP 7.

For example: put the following test.jsp in your web application (e.g. example.war)

<% request.setAttribute("testAttr", "01"); %>
${testAttr == 1}</br>
${param['foo'] == 1}<br>
${1 == param['foo']}<br>
${1 == (0+param['foo'])}<br>

Then, access the above JSP with the following curl command:

$ curl http://localhost:8080/example/test.jsp?foo=01

EAP 6's expected result:

true<br>
true<br>
true<br>
true<br>

EAP 7's actual result:

false<br>
false<br>
false<br>
true<br>
