Eclipse JDT error when trying to run tests

[veredcon]

Hi I get:

I have installed https://github.com/microsoft/vscode-java-test/releases/tag/0.22.1 vscode extension in theia based IDE (0.22.3 currently does not work).

Running test pops up this error:

This is Java Maven spring boot based application and in VScode windows enviorment the same project runs successfully.
The project: git clone https://github.com/SAP-samples/cloud-cap-samples-java.git

This is the log I get in the Java log file:

Hmm, I'm not sure what's the differences between VS Code and Eclipse Theia. Is that because some capabilities of VS Code are not supported in Theia?

[veredcon]

After giving it more thought, might it be related to the Java we are using in theia?
Maybe trying to install Java JDK in later version than 8 would solve this issue?

[jdneo]

Hmm, I'm not sure of that. JDK 8 should be ok. I'm also using JDK 8 before.

[veredcon]

Thanks. As far as I know in our environment we are installing JRE and not JDK so maybe this might be the root cause
