Java errors on creating a new Simulink model (R2014a, Mac OS X 10.9.3)

Hello,

I have Matlab+Simulink (no Toolboxes) installed on a MacBook Pro using Mac OS X 10.9.3 (Mavericks). Matlab+Simulink are Version 8.3 / R2014a. Installation happened without any errors, activation worked, too.

When I start up Matlab, the Matlab main window starts up normally without problems. When I then click "new"->"simulink model", a lot of Java Errors are shown at once red in the Matlab Window. After a few seconds, the Simulink Window appears.

So in the moment I do not know, how to get rid of those Java errors.

I read several threads about similar problems, but I assume there can not be a wrong Java version because the newer Matlab versions seem the carry their own Java version with them. When I check this, there are different Java versions shown out of Matlab and out of Mac OS X.

When I enter "version -java" in the Matlab Window it shows Java 1.7.0_11-b21 with Oracle Corporation Java HotSpot™ 64-Bit Server VM mixed mode

When I enter "hava -version" in the Mac Shell, it shows java version "1.8.0_05" Java™ SE Runtime Environment (build 1.8.0_05-b13) Java HotSpot™ 64-Bit Server VM (build 25.5-b02, mixed mode)

So what else can I do?

I would recommend contacting MathWorks Support about this.
