Hi,
I just got a Windows computer (Win10) and just installed Matlab 2019b. When I launch Matlab, I keep having this error message:
Warning: Unrecognized token "$null " in Java path specification.
Warning: Unrecognized token "$null " in Java path specification.
Warning: Unrecognized token "$null " in Java path specification.
Warning: Unrecognized token "$null " in Java path specification.
Warning: Unrecognized token "$null " in Java path specification.
Warning: Unrecognized token "$null " in Java path specification.
Warning: Unrecognized token "$null " in Java path specification.
Warning: Unrecognized token "$null " in Java path specification.
When I check the Java class path, this is what I get:
>> javaclasspath('-static')
STATIC JAVA PATH
C:\Program Files\MATLAB\R2019b\java\...
(I croppped all the subfolders in the output tree here).
As for the dynamical pathway:
>> javaclasspath('-dynamic')
DYNAMIC JAVA PATH
<empty>
I have no idea what to do and cannot find anything on the web. If anyone has an idea, I would really appreciated it.
Thank you for your help!
