Virtualbox plugin : failed to launch slave agent via java web start

[He Chen]

Hi,

I used the folk on Github which supports virtualbox 5.1.6. Then I installed and configured the node, it could run the virtualbox after I clicked  the launch button, but it always failed to set the agent online. The log is shown below.

I have Jenkins ver. 2.89.2 and virtualbox 5.1.6 with win10
