It is fixed in JDK9, but not officially backported. There are several issues from java.util.concurrent treated like this. The backport exists as a part of enhancements of JSR166  - http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/jdk8/java/util/ , but it is not a part of any update of JDK8.

The changes were done as a bulk update for 9:


which includes some slight specification changes that may not be 
suitable for an update release. Individually backporting those changes 
that can be backported is doable but you have to find someone to 
actually do it. Not all bug fixes are automatically backported.
