TomEE starts but Netbeans gives "Failed to start" error

Question

I'm using NetBeans 8.0.2 (also, tried it in the latest nightly build) and trying to start TomEE Plume server on port 8084 (tried it on different port too). Server starts and works fine, but NetBeans thinks it is not started and after approximately 2 minutes of waiting ("Waiting for Tomcat") throws an error window "Tomcat failed to start" or something like that.

There are questions similar to mine with the difference that I have totally no errors, only "Tomcat failed to start" window, so I can't even put the log here as it says nothing useful. Also, available solutions are not working for me.

I believe that there's some communication problems between NetBeans and TomEE, also I'm almost sure the problem is in NetBeans because TomEE works well and starts as it should, localhost:8084 gives me Tomcat page though NetBeans think it failed to start. There's some small chance that for some reason TomEE is not sending confirmation to NetBeans after starting, but I really have no ideas how to check that.

I've looked into the same issues, two most common problems are "'127.0.0.1*' is not recognized as an internal or external command" and the very same I have. Solution suggested was to choose "No proxy" in the Tools-Options, still it didn't help me.

Also, just to be sure, I've edited catalina.bat file and checked my user permissions that are roles="admin-gui,manager-gui,admin,manager-script".

I hope someone faced the same issue. Also, I'd like to know is this problem even solvable. Thanks.

NetBeans 8.0.2 was working well with TomEE+ 1.7.1, but then I upgraded from TomEE+ 1.7.1 to 1.7.2, added TomEE+ 1.7.2 in Services > Servers in NetBeans 8.0.2, and that's when I experienced the 'Failed to start' error while running latest-and-patched NetBeans 8.0.2 and TomEE+ 1.7.2.

In server.xml, I had the following:

<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
           maxThreads="150" connectionTimeout="20000" acceptorThreadCount="2"
           redirectPort="8443" socket.directBuffer="false"/>

I attempted to modify the Connector, but that did not fix the issue.

The fix for me was to uncheck the Use IDE Proxy Settings checkbox on the Platform tab of the Server properties of Apache TomEE+ 1.7.2. See below.
