Using NB8 with jdk8 compile of my client project moves from about 20 seconds to about 2 minutes.  Move back to jdk7 and it goes back to normal.  Appears to be a defect in jdk8 but has negative impact on NB8.  It also appears NB8 has stopped working during this time when one core is @ 100% and the rest are working on lesser tasks.  The 100% core changes from time to time but one core is always @ 100%.  This is not true in my typical compile.

This is on 64 bit Linux but I've seen in nbusers other victims on windows and one person is complaining about NB8 hanging on a Mac. These could be also related to the jdk8 issue rather than NB8.
