jvmRoute as a property

[jean-frederic clere]

Hi,

I would to add a feature: Allow jvmRoute to be a system property.

I have several Tomcat's using the same server.xml but I need a different sessionId for each Tomcat. The easy solution I have found is to use jmvRoute="SYSTEM" and read the system property "jmvRoute" to have the jvmRoute I want.
I have enclosed the corresponding patch.

Should I commit it?

Cheers

Jean-frederic
