Nick Boldt commented on JBDS-4149:
----------------------------------

I restarted the above rpm install, then:

* Help > Install new software > browse to /home/nboldt/tru/jbosstools-browsersim/site/target/repository where I built ibuziuk-JBDS-4149 fork (the PR above - https://github.com/jbosstools/jbosstools-browsersim/pull/90 ) > install new Browsersim
* Now when I close the Browsersim window, no error is thrown or logged. 

+1 for this PR.
