Undertow servlet 'check-interval' attribute not working

UPDATE:
In the end, there was just a description update provided to the /subsystem=undertow/servlet-container=default/setting=jsp[check-interval] attribute. Since it describes a reason why this attribute might not be taken into account, I think it is ok to go with.

After the discussion in this Jira, this attribute should be marked as deprecated actually. Therefore there need to be done:

1. provide information that this attribute is deprecated in resource description in CLI for /subsystem=undertow/servlet-container=default/setting=jsp[check-interval] (since what version + reason)
2. provide such information also in our EAP7 documentation

As from discussion following text is irrelevant for now

Attribute

/subsystem=undertow/servlet-container=default/setting=jsp[check-interval]

of JSP servlet configuration seems not to be working - whatever is its value, any change to JSP file is propagated to EAP server right after the file change.

Try following with various values set to check-interval attribute:

1. start EAP server
2. deploy any war with jsp file (e.g. attached simple-jsp.war) as an exploded archive
3. perform request to localhost:8080/simple-jsp to see content
4. modify file EAP_HOME/standalone/deployments/simple-jsp.war/index.jsp
5. perform request again and see that change to file was directly propagated

Expected behaviour is:

• when check-interval is set to 0, then no check for JSP updates is performed at all
• when check-interval is greather than 0 and developement is false, then regular check for JSP updates is provided each X seconds, where X is value of check-interval attribute

In EAP6 this seems to be working just fine this way.
