Yes, I noticed the tab problem too. Fixed.

The waitForInput() method waits for input on stdin. There is no process that provides that input so it’s not necessary. The reason it works before my change is that System.in.read() returns -1 (end of input) when run in “othervm” mode. With the “driver” change I wanted the tests to be able to run in “agentvm” mode and there System.in.read() blocks. I haven’t delved into the details of why, but since there is no reason to wait for input here I simply removed the line. I should have mentioned this in the review request.

Thanks,

Specifying “@run driver” (instead of “@run main”) will launch the test with no vm arguments. Whatever arguments were specified in -vmoptions to jtreg will be available in the System property test.vm.opts and the test code can use those arguments when launching other processes.
