Error trying to find JVM: Unexpected output from `java -XshowSettings:properties`. Didn't find all expected properties: java.version,java.home

I get the following error: Error trying to find JVM: Unexpected output from java -XshowSettings:properties. Didn’t find all expected properties: java.version,java.home

I suspect this is because in my env var I have set JAVA_HOME to JDK 6. Unfortunately I won’t be able to change that. I do have JDK 8 installed which is referenced through java.home VSCode settings for/by another plugin. Can you please add similar or reuse same setting to support configurable JDK?

The new configuration key is called spring-boot.ls.java.home. I’ve also reorganized a bit so that the existing key for configuring jvm heap size is now called spring-boot.ls.java.heap.

I’ve also made similar changes in the other language servers for concourse, bosh and cloudfoundry-manfiest. They have keys called:

• concourse.ls.java.home
• concourse.ls.java.heap
• bosh.ls.java.home
• bosh.ls.java.heap
• cloudfoundry-manifest.ls.java.home
• cloudfoundry-manifest.ls.java.heap

All language server vscode launching code is shared and uses the same logic. The only difference is the name of the first part of the configuration key.

I think we were already planning on doing that but didn’t feel like this was urgent/critical. But it sounds like we should prioritize that.

Maybe you can. It might be possible to change the JAVA_HOME env var only for the vscode or STS process without changing the global env var setting used system wide.

I’m not sure this will work for you, as I’m not sure exactly why you need it be a JDK6. But you could just set the env var when launching vscode. For example on Linux I could so something like this when launching vscode from a CLI terminal.

JAVA_HOME=/opt/alternate/javahome code

This will set JAVA_HOME only for that one time, launching vscode process.

To avoid having to do it everytime you launch vscode you could also create a shell script and put the launch command with env var setting in there.

So maybe that could be a workaround for you until we add a proper vscode setting.
