Upon more investigation, we determined that the problem is in jtreg's handling of `@run driver` in `jtreg -othervm` mode. This should be fixed in the upcoming release of jtreg.

Since this issue affects not just OldClassTest.java, I don't recommend fixing this test case individually. Instead, I would recommend using `jtreg -agentvm` as a work around for now.
