Why starting JBoss Fuse as a service wrapper hangs for ever without internet access?

Issue

• While starting the JBoss Fuse as a service wrapper it hangs at the following logging:

From the logs it is hanging here:
11:04:27,791 | INFO  | -610328-thread-1 | BlueprintExtender                | 12 - org.apache.aries.blueprint.core - 1.0.1.redhat-610328 | No quiesce support is available, so blueprint components will not participate in quiesce operations

• If we try to start fuse with the initial "$JBOSSFUSE_HOME/bin/start" instead of the wrapper script the server starts ok.
• The box where the fuse is being attempted to be started as a service is not connected to the internet.
