I agree. Keyboard shortcuts should be disabled to achieve consistent results across different devices for jtreg tests. There's a guideline and a list of setting changes here: https://wiki.openjdk.org/display/ClientLibs/Automated+client+GUI+testing+system+set+up+requirements

I think changing the key-binding here is not necessary after changing this setting. I recently also had this failing test (and possibly failing subsequent tests) because my device had keyboard shortcuts enabled. But after removing the shortcuts, the test passed (and others).

I'd recommend disabling keyboard shortcuts and trying your tests again to see if it's still reproducible.
