From above I can see that there are 4 open vscode windows, each has 3 Java process.

• org.eclipse.xxx is Java LS provided by vscode-java extension
• BootLanguageServerBootApp is Spring LS provided by spring tools extension
• XMLServerLauncher is provided by vscode-xml extension

RAM consumption is far exceeding expectation.

Boot LS is eating RAM, which is strange. I tested locally with spring-petclinic, and BootLS takes ~120MB of RAM. Maybe it's due to project scale. I'm not sure if the "demo" projects are related to https://github.com/Netflix/conductor , and a sample project would be very helpful.

Heap Mem: 30~40M
Non-Heap Mem: ~80M
GC works well.
