jalview.bin.MemorySettingTest fails when run from gradlew but passes in Eclipse

Default eclipse config with the refactored build tree seems to execute tests directly via the workspace configured jvm (ie 17, 21, or 25), and all pass.

When gradlew runs on the command line it downloads an 11 jvm - which it uses to execute tests. This configuration doesn't let jalview.bin.MemorySettingTest pass. Annoyingly ./gradlew jalview-app:test doesn't provide an option to report stdout/stderr so no obvious issues are revealed.

Manually configuring eclipse to run the testng tests using the same jvm reveals stdout/stderr like:
