leaves zombie processes
See original GitHub issueIssue Type: Bug
Using the extension and exiting/reloading vscode leaves zombie (defunct) java processes on the host.
I’m using “Remote: SSH” to work (remote is Linux, local is Windows).

Part of this is a known issue which should be fixed by https://github.com/redhat-developer/vscode-java/issues/1928. When we adopted languageclient v7, shutdown requests sent to the syntax server were not being handled correctly, so in our next release, we have a workaround.
The zombie process behaviour could be an issue with remote connections given that it seems to happen for any language server (syntax, standard) that’s started up.
