Hi,
Please review the fix (extra small) for: bug 8194154: https://bugs.openjdk.java.net/browse/JDK-8194154 webrev: http://cr.openjdk.java.net/~minqi/8194154/ Summary: canonicalize will check and fold double (or more) slashes, but in function collapsible(char*) and splitNames(char*, char**), it failed to process strings like "//". This results in the former does not give a correct number of substrings and the later does not give a correct array of substrings. The fix add a check if the character is '/' after a '/'. The JDK has never supported setting user.dir in this way (it breaks several things). There is a thread discussing this on core-libs-dev so best to bring it to that mailing list to discuss again.
