I messed with the version of Java that I was using in Matlab and then I had some issues, so I tried to delete Matlab and all versions of Java from my machine then reinstall Matlab. According to,
Matlab already has java in it, so I assumed that the fresh install of Matlab would fix the issue. But it did not and I ended up having to install Java and point to it as per the article above just to get Matlab working with Java again.
The issues are these:
1. When I start up Matlab, I get
2. Sometimes it spools red errors and I have to shut Matlab off
3. I loose a lot of the interactive features, for instance; I cannot click on the folder ribon to move through the folders as:
3.b also, sometimes I cannot resize windows.
So, I lost some functionality. How can I run the version of Java that ships with the student version of Matlab?

Hi, yes the cause of this issue appears to be the use of an incorrect JRE . Here is my recommendation - when MATLAB is shipped, the JRE used by the installed product is located in the directory (example for R2015a , win64):
C:\Program Files\MATLAB\R2015a\sys\java\jre\win64\jre
The JRE used by your current running instance of MATLAB can be determined by the output of the following command:
>> java.lang.System.getProperty('java.home')
Ideally, the output from the above command must point to the shipped JRE. I would recommend changing your MATLAB_JAVA environment variable to point MATLAB to use the shipped version of the JRE. This should resolve the issue.
