OSX Blocking JNLP Launch Java1.8U40 - Anyone Know Why?

We deploy our application as a JNLP launch file and/or as a webpage applet.

I have a customer that updated his MAC OSX system to the latest Java Version 1.8_40. After upgrading the JNLP launch stopped working. It seems to start Java (flashes blue java logo) then stops. No Exception is thrown. I suspect yet another OSX security hurdle.

Anyone else out there see this? Any clues about what is causing the issue?

Our guess is that the cause of this bug has been backported to 8u40. We find that the application cannot get focus once the new blue Java splash screen is shown. We can also reproduce this on all the demo webstart apps on Oracle's own site, so it isn't our code.

You can confirm this bug by running your webstart instance with -Xnosplash to skip that splash screen. Unfortunately you cannot add that parameter to the jnlp file.

We can only reproduce this problem on OSX 10.10 (Yosemite).

A workaround (if you can control the client Java settings) is to add "-Xdebug" in Java Control Panel -> Java -> View... -> Runtime Parameters.

Update: the bug has been fixed and backported to 1.8u40. Oracle have also silently updated their downloads to the new build (1.8u40b27) as can be seen here I don't know that people already running 1.8u40 will get an update automatically.

When i add '-Xdebug' in the Java Control Panel as a Runtime Parameter it works for me.
