New Revision: 1004684

URL: http://svn.apache.org/viewvc?rev=1004684&view=rev
Log:
Added a method to check whether the deployment task is running. If an Axis2 
server is shutdown while the deployment task is running, there can be 
exceptions that are thrown. So. in a graceful shutdown scenario, we can first 
check whether the deployment task is running, and then initiate the shutdown 
procedure, once the task has ended.
