The following are some of the notable bug fixes included in this release:
 

jps running as root fails after the fix of JDK-8050807
When running jps as root in solaris or linux, it should be able to display process information for all running java process in the system. This worked fine until 7u72:
For example:

jps running In 7u72 solaris machine:
7u72/bin/jps
1771 ControlPanel
722 Bootstrap
1224 ContainerPrivate
1637 swupna.jar
1772 Jp

jps running In 7u75 solaris machine:
7u75/bin/jps
1746 Jps
1739 -- process information unavailable
722 -- process information unavailable
1224 ContainerPrivate
1637 -- process information unavailable

This bug was introduced when fix JDK-8050807 was merged in JDK repository. In this fix UID of directory is matched with the effective Id of process. When JPS command is executed as root, it tries to read the process information from "/tmp/hsperfdata_$username_$ProcessID" file. Before reading the process file or directory, it checks if the file or directory is secure or not. It opens the user directory and match the UID of that directory (which belong to other user) with the current process(root-jps) effective ID,which gets fail and process returns failure.

See JDK-8075773.

"Apply" button is permanently disabled in JCP, after roaming profile option is changed
After the option "Store user settings in the roaming profile" located in "Java Control Panel -> Advanced -> Miscellaneous" is changed and applied by a click on "Apply" button in Java Control Panel (JCP), "Apply" button becomes permanently disabled and changes of any other options in JCP do not lead to enabling of "Apply" button.

See JDK-8133985.

JFR reports abnormally high machine CPU consumption on Linux
On Linux kernels 2.6 and later, the JDK would include time spent waiting for IO completion as "CPU usage". During periods of heavy IO activity, this could result in misleadingly high values reported as CPU consumption in various tools like Flight Recorder and performance counters. This issue has been resolved.
