             Summary: Can't launch (and connect) NetBeans from node
                 Key: NETBEANS-3101
                 URL: https://issues.apache.org/jira/browse/NETBEANS-3101
             Project: NetBeans
          Issue Type: Bug
          Components: platform - Launchers&CLI
            Reporter: Jaroslav Tulach


 

I am trying to connect to a *NetBeans* based application from _Visual Studio_ - 
aka _Electron_ - aka *node*. Somehow the *node* mangles network setup and the 
InetAddress.getHostAddress() isn't the same. To reproduce create following 
structure of files:
{code:java}
$ ls -l | cut -c50-
dump.hprof
nb.js
nb.sh
netbeans -> /home/devel/bin/netbeans/bin/netbeans
$ cat nb.sh 
./netbeans 'dump.hprof'
$ cat nb.js 
var exec = require("child_process").execFile;
let path = './netbeans';let vvm = exec(path, [ 'dump.hprof' ]){code}
Then start *./netbeans* on background and wait for the GUI to launch. Then do 
following from command line:
{code:java}
./jvm.sh
{code}
The dump.hprof file opens in the the GUI. Close it and try the same via 
*node.js*:
{code:java}
node ./jvm.js
{code}
The heap dump isn't shown (on my computer), rather a warning dialog appears. 
Result of node and shell script disagreeing on what is local host address. One 
is using IPv6 and one IPv4.
