Jaroslav Tulach reopened NETBEANS-3101:
---------------------------------------
      Assignee: Jaroslav Tulach

At the end the fix may be needed for the [VSCode extension|https://github.com/apache/netbeans/tree/master/java/java.lsp.server/vscode] running on GraalVM/JDK8. It is [launching NetBeans from code|https://github.com/apache/netbeans/commit/fa22d9c0508e6b8a15a2dfb07ee8c4b7ef6c1a99#diff-7eb3c296ad0e55de616ce54ff7993a4aL63]. It cannot use the {{[ignore, ignore, ignore]}} trick as the LSP client needs stdio to talk to the server.

As such I [integrated the here in proposed patch|https://github.com/apache/netbeans/commit/005d869d0d47afac38dbfca6c244a2054e98a9a9] into the {{java-lsp-server-debugging-attempt2}} branch. Now the GraalVM/JDK8 support is working.

> 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.
