How can I resolve a Java error when launching Matlab 2012a?

We have installed Matlab 2012a onto our business machines but have come across a slight issue. The software has been installed with full admin rights and has installed successfully.

When the user logs back in and runs the application the software fails to load and a Java log is generated:

A fatal error has been detected by the Java Runtime Environment:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00000000, pid=3980, tid=4484

 JRE version: 6.0_17-b04
 Java VM: Java HotSpot(TM) Client VM (14.3-b01 mixed mode windows-x86 )
 Problematic frame:
 C  0x00000000

We have tried on multiple machines and get the same issue. The user has been added to the admins group but this is also causing the same error.

Java has been re-installed but this has made no difference.

Does MATLAB launch without Java?

matlab -nojvm

or

matlab -nodesktop

[RWE]

I can confirm that Matlab will launch with the -nojvm command although only as Matlab command (Which I assume is expected)

It dosn't alunch with the -nodesktop command

The machine is running JRE 7.

I am not sure what platform you are on, but Java 7 is not the supported version of java. You may have changed the java from the default that MATLAB uses manually if it is Win or *nix OS. MATLAB ships its own Java for this platforms and only that is tested and must be used. To change the Java back remove the env variable MATLAB_JAVA

If you are on Mac, things are tricker. Provide some more information about your system if the above doesn't work.
