Openjdk is being treated as invalid JDK on vscode for linux

Issue Type: Bug

The following error is received on Configure Java Runtime Extension Page of the Language Support for Java Extension:

This path is not pointing to a JDK.

But java commands are working alright in the terminal.

echo $JAVA_HOME gives /usr/share/java/jdk-11.0.4 and java --version produces this output:

openjdk 11.0.4 2019-07-16 OpenJDK Runtime Environment (build 11.0.4+11-post-Ubuntu-1ubuntu219.04) OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu219.04, mixed mode, sharing)

Extension version: 0.50.0 VS Code version: Code 1.39.1 OS version: Linux x64 5.0.0-31-generic snap

Hi @tarun0,

I had a similar issue on Ubuntu 19.10. Installing openjdk-11-jdk explicitly fixed it. The directory /usr/lib/jvm/java-11-openjdk-amd64/ contained a jre before installing the jdk.

Same issue. OS: Ubuntu 18.04.3 LTS

ls -la /usr/lib/jvm/java-11-openjdk-amd64 gives following output (after changing the owner to tarun from root but even that didn’t solve)

drwxr-xr-x 7 tarun root 4096 Dec 16 15:06 . drwxr-xr-x 3 root root 4096 Dec 16 15:06 … drwxr-xr-x 2 tarun root 4096 Dec 16 15:06 bin drwxr-xr-x 4 tarun root 4096 Dec 12 15:11 conf lrwxrwxrwx 1 tarun root 42 Jul 18 23:51 docs -> …/…/…/share/doc/openjdk-11-jre-headless drwxr-xr-x 72 tarun root 4096 Dec 12 15:11 legal drwxr-xr-x 6 tarun root 4096 Dec 16 15:06 lib drwxr-xr-x 4 tarun root 4096 Dec 12 15:11 man -rw-r–r-- 1 tarun root 1161 Jul 18 23:51 release

Below is the complete error (doesn’t point to jdk)
