With enabled proxy without username/password I got an NPE for check-availability

[ahoehma]

I'm working behind a company proxy and if the proxy is enabled for maven then
"mvn beanstalk:check-availability" throws an NPE:

I'm able to run the plugin if I provide empty tags for the proxy (our company proxy doesn't need a login):

<username></username>
<password></password>
