      Description

        There are a lot of jtreg tests that use temporary files. These temporary files add up over time and fill up the global temp directories on our test systems. To tackle this, we should try to redirect these temporary files into a directory controlled by the test framework. Jtreg does not do this, but we can set -Djava.io.tmpdir from RunTest.gmk. This will not prevent all temp files from being created outside of the work dir, but at least most.

        I have found one test where this becomes an issue, java/nio/file/Path/Misc.java on Windows when running in elevated mode with the workspace on a subst drive. This looks like an actual issue in the product, so will file a separate bug for it.
