How to exclude the Java virtual machine from astand-alone application?

I want to use the mcc compiler to generate a stand-alone application to run on a shared cluster. Due to memory restrictions, I want to exclude jvm. I use

mcc -m -R -nojvm -R -nosplash -R -nodisplay -R -nodesktop -R -singleCompThread -I [included directories] -o application_name

During compiling, I get the message:

Warning: You have specified '-R -nojvm', which may restrict or eliminate MATLAB graphics functionality at runtime.

That sounds good. Now I set

ulimit -v 1000000

because that is the setting on the shared machine. Then I run

sh run_application_name.sh $mcrroot

with $mcrroot pointing to my Matlab runtime installation. The results is:

------------------------------------------ Setting up environment variables --- LD_LIBRARY_PATH is .:/usr/local/MATLAB/R2016a//runtime/glnxa64:/usr/local/MATLAB/R2016a//bin/glnxa64:/usr/local/MATLAB/R2016a//sys/os/glnxa64:/usr/local/MATLAB/R2016a//sys/opengl/lib/glnxa64 Opening log file: /home/veen/java.log.20374 Fatal Error on startup: Unable to start the JVM. Error occurred during initialization of VM Could not reserve enough space for object heap

There is not enough memory to start up the Java virtual machine. Try quitting other applications or increasing your virtual memory. ----------------------------

What am I missing? It seems that the JVM is started anyway. Moreover, if I compile again right away (on the same machine and terminal) I even get the "Unable to start the JVM" message at compile time!

Which version of MATLAB are you using to compile the standalone application? Can you try creating a standalone with the -nojvm option for the following code?

This code should fail by throwing 'Error using gcf' since the application tries to use the JVM then the compiled application does not support it.
