"vm.install.path" Server Parameter doesn't work - WIN10

[davigre]

I use Wildfly-10.0.0.Final with JDK_8_251.

All was working ok, but now redhat-developer/vscode-java needs JDK 11+ so I change java.home to C:\\Program Files\\AdoptOpenJDK\\jdk-11.0.8.10-hotspot.

The problem is that 'Server Connector' normally tries to run Wildfly with 'java.home' JDK.

Reading the manual I add "vm.install.path": "C:\\Program Files\\Java\\jdk1.8.0_251" to run Wildfly with JDK8, but the following exception is output as soon as I save the configuration:

The server management server is running on port 8500

and when I try to 'start the server':

And when I reopen vscode in output 'Red HatServer Connector (stdout)':

Thanks for opening this issue @davigre. I was able to replicate this. I'll give it a look asap.

@davigre we just released the new server connector extension (0.23.3) which fixes the issue with the vm.install.path property. Now you should be able to set it up and use rsp-server with the latest vscode java. Let us know if you face any other issue. Thank you and sorry for taking so long.

@lstocchi ,

Thanks a lot. I already tested.
