JUnit test detection fails with java.io.FilePermission on local run with emulate cloud security enabled

[dlhartveld]

JUnit test detection fails with java.io.FilePermission on local run with emulate cloud security enabled.

In 6.10.3, new apps by default have cloud security emulation enabled. Workaround is to disable cloud security emulation, but this is not documented. Sidenote: JUnit tests are only detected if a constant is set to true. However, this is also undocumented.

Log output:

Unable to find JUnit test classes or methods.

[RoelandSalij]

Does the error also occur in the 'cloud'?

[dlhartveld]

Sorry, I did not try that and don't have a cloud node available to try it, unfortunately.

Thanks! 👍
