Brian Stansberry commented on JBAS-8259:
----------------------------------------

The ProcessManagerSlave class looks like a big piece of 1) and 2) from the JIRA description. Just need to pass in different streams.

> Default communication mechanism between SM and PM is via stdio. This should almost always be fine, since we use the jboss-stdio lib to capture application usage of stdio and preserve the original streams for our own use. But there is a slight possibility that an extension module running in the SM will use JNI, which can pollute the stdio streams.
> So, we need an option to allow users to configure SM-PM communication via sockets. (The same issue applies for Server-PM and Server-SM communication, but there the SM can parse host.xml and get configuration from it, so the details are different from this SM-PM use case.)
> Tasks:
> 1) Put SM-PM communication behind an abstraction
> 2) Implement stdio-based and socket-based versions of the abstraction
> 3) Modify process manager module to accept PM socket configuration via command line params
> 4) PM passes it's socket configuration to SM via command line when it starts PM
> 5) Decide how to configure SM's socket -- via host.xml?  (Note SM needs a socket for communication with the DC -- use that?)
