If this is a test environment, any chance you can add the following line to your `data/ignition.conf` file under the `# Java Additional Parameters` heading (updating the number 6 if necessary)?

```auto
wrapper.java.additional.6=-XX:-OmitStackTraceInFastThrow

```

On restart, in theory, it should start providing a stack trace.

Thanks,
