Matlab coder java.awt.AWTEventMulticaster.hierarchyChanged(AWTEventMulticaster.java:498)
显示 更早的评论
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 Maria,
I have the same issue, I think.
When I check for issues with the matlab coder app, some times the following error is printed in the matlab command prompt:
Exception in thread "AWT-EventQueue-0": java.lang.StackOverflowError
and after that, for 1024 times,
at java.awt.AWTEventMulticaster.hierarchyChanged(AWTEventMulticaster.java:498)
when this happens, matlab freezes for minutes.
Could you fix your problem?

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.
