Tried to run a simple Web Application using NetBeans 8.0.2 and 8.1 RC2 and use WildFly 9.0.0.Final application server. The first run seems to work fine but subsequent run gives the error: Caused by: java.net.BindException: Address already in use at sun.nio.ch.Net.bind0(Native Method) at sun.nio.ch.Net.bind(Net.java:433) at sun.nio.ch.Net.bind(Net.java:425) at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:223) at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:74) at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:67) at com.sun.corba.se.impl.transport.DefaultSocketFactoryImpl.createServerSocket(DefaultSocketFactoryImpl.java:83) at com.sun.corba.se.impl.transport.SocketOrChannelAcceptorImpl.initialize(SocketOrChannelAcceptorImpl.java:161) ... 16 more Plugin should detect the error and not try to run the application server again. Seems like I may not be able to showcase this during JavaOne session coming up in another 20 mins.
The plugin is detecting that the application server is running by testing the management connection. As for the Http server port, this is now taken from the configuration wizard. For 8.0.2 if you are not using 'my' release on the plugin portal then WF9 is not working.
Is this updated plugin also required for 8.1 RC2 which was released a few days ago?
Nope, only for 8.0.2 As for 8.1 I don't know what's in RC2 but I think the profiler issue and maybe one or two others were fixed after the rc release.
