Hello Christian, the `TEST.ROOT` (and `TEST.properties`) appear to follow the camel case style property names for most of the configurations https://openjdk.org/jtreg/tag-spec.html#TEST_ROOT. For example, `defaultExecMode`, `maxOutputSize` and so on. To be consistent with that, maybe we should expect this to be `defaultTimeoutSeconds` instead of `timeout.default.seconds`?
