Cannot connect to Karaf shell when starting JBoss Fuse from within JBoss Developer Studio

Issue

I am using JBoss Developer Studio (JBDS) 9.1 on Windows and configured the Servers View to manage an instance of JBoss Fuse 6.2.1.
When starting JBoss Fuse from JBDS, it starts up fine but I am unable to open an SSH client connection to the Karaf container. The connection either hangs or raises

Error connecting localhost:8101 : SSH client error: Session.connect: java.net.SocketTimeoutException: Read timed out.

When launching JBoss Fuse from the DOS command line, I can connect to the Karaf console just fine, using bin/client.bat as well as from JBDS SSH connection.
