Hi,

regards.

[llgcode]

Seems to correspond to this commit:
eclipse-jdtls/eclipse.jdt.ls@bae72c2

It feels like your build dependencies are not sync with runtime deps

[llgcode]

I've uninstall/install the java bundle extensions and it works now.
I don't know what happen ?!!

[jdneo]

Maybe some OSGi cache issues? Anyway, it's good to know problem is gone.

[zergeborg]

@jdneo Can this may be reopened? I see the exact same error on my Mac using v0.39.1 of this plugin. But even downgrading the extension did not help.

[jdneo]

@zergeborg Please use latest 0.40.0 https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-test

[zergeborg]

@jdneo Thanks for the prompt response! I can confirm the error is gone with 0.40.0
