JBDS-2515 - Scan ~/jboss-runtimes automatically

https://issues.jboss.org/browse/JBDS-2515
JBDS70_0011: [Commit] (Dev) (P3) Scan ~/jboss-runtimes automatically
Why would you call RuntimeInitializerUtil.initializeRuntimesFromFolder if directory is null or not a directory? i.e. why no put that down in the if block below?
