I change last week to Java 8 (JDK 1.8.0_40) on my Mac. After that I noticed some trouble:

- there ist no icon in the task bar after the start of tmm
- tmm ist in the task list (CMD-TAB)
- the progressbar in the lower right corner shows no progress
- the mouse cursor is not changing at the corners of the main window
- the application does not terminate. I have to kill it on the command line (simple kill, not with -9)

Does anyone have these problems? It worked fine for months with JDK 1.7.0_71.

I've heard several times that there is a severe problem with Java 8u40 on OSX (see http://stackoverflow.com/questions/28865...e-know-why ).
Maybe all your problems result from this bug too?

you could either try to:
a) downgrade to java 8u31
b) or try the provided workaround in the stackoverflow thread (A workaround (if you can control the client Java settings) is to add "-Xdebug" in Java Control Panel -> Java -> View... -> Runtime Parameters.)

Thanks for your reply. Workarounds did not work. I found no solution to switch back to Java 7 without deinstalling Java 8.
So I removed all JVMs and installed 1.7.0_75. Now it is working fine again. So Lamdas and new DateTime have to wait

or just try to install Java 8u31 - this version works
