Hi,

I am running the Matlab Coder to generate a mex function. When calling the testing function, that should "exercise" the mex function, I get this red message

java.awt.AWTEventMulticaster.hierarchyChanged(AWTEventMulticaster.java:498)

However, one the testing function is done, I can still create a mex file. Is it something I should be worried about?!

Hi,

Yeah. This message keeps showing during "Running test file with MEX" for me too. But the test runs seemingly without any problem.

I often run in the same issue. Today again. I got it with the slightly more complex projects I run in ML Coder. It happens often after using the Coder app for multiple iterations in the 'Check for run-time issues' tab, each time correcting small coder incompatibilities in my underlying Matlab code. After a while it seems like some memory issues play up and give this error (which is 100-1000 of lines and stalls the system for a while).

In my case simply restarting Matlab and continueing solves the problem for a while.

As an extra note: I got the feeling it especialy plays up when there are difficult to asses errors/incompatibilities in my code which often only show up when running the mex.
