Spring Boot Tools for VS Code incorrectly misidentifies internal JDK for Language Support for Java as a JRE

[alvint]

Now that Language Support for Java is platform-specific, it embeds a JDK by default. On my linux VM (which I connect to via Remote-ssh), the path to this JDK is ~/.vscode-server/extensions/redhat.java-1.2.0/jre/17.0.1-linux-x86_64/.

However, if I try to use this JDK for Spring Boot Tools by setting spring-boot.ls.java.home, it complains that it's a JRE (see picture). My guess is the extension is simply checking the path for the string "jre" to determine if it's a JRE or JDK.

The way I see it, there are two issues that need to be addressed:

• a more robust check needs to be done to determine if the folder is a JDK or JRE
• since Spring Boot Tools requires Language Support for Java, and Language Support for Java now includes a JDK by default, Spring Boot Tools should scan for and automatically use this JDK by default, if it's not overridden by spring-boot.ls.java.home (OK, this part is more of an enhancement)

To reproduce, set spring-boot.ls.java.home to a JDK whose path includes the string "jre".

@kdvolder and I fixed it:

• Better criteria for JDK d71b70b
• Use embedded JDK into java ls if it is around 29db241

Works great here. Thanks!
