Hi,
Please review the following improvement that caches default ZoneId
object and makes the frequently executed ZoneId.systemDefault() method
faster:
http://cr.openjdk.java.net/~plevart/jdk9-dev/ZoneId.systemDefault/webrev.04/
The patch is just a rebased version of webrev.03 + some comments added
about the importance of defensive cloning in TimeZone.setDefault().
There was already a discussion about this patch a while ago and Stephen
basically approved it in this form:

Thanks,
