There are couple of stability issues on Windows arising from the move to the VS2010 compiler a few builds okay. One them is that File's getCanonicalPath and a few others methods crash the VM when the dealing with an invalid drive. This turns out to be regression in the new C runtime library with the _wgetdcwd function. We're following this up with Microsoft but for now, we can workaround this by verifying that the drive is valid. The webrev with the proposed changes is here: http://cr.openjdk.java.net/~alanb/6983520/webrev/
Thanks, Alan.
