"MATLAB is exiting because of fatal error" when invoked from compiled java library

The .m file is a quite simple test, just invoke bwmorph, it works fine in matlab GUI:

function [outputFile] = matSkel(inputFile,method)
%MATSKEL Summary of this function goes here
%   Detailed explanation goes here
clear img
img=imread(inputFile);
img=bwmorph(img,method,Inf);
imwrite(img,inputFile);
outputFile=inputFile;
end

Then compile into library jar with deploytool, if invoked in JVM, the error appears:

_ _ _java: <unknown>:0: <unknown>: Assertion `This application failed to start because it could not find or load the Qt platform plugin "xcb".

Available platform plugins are: linuxfb, minimal, offscreen, xcb.

Reinstalling the application may fix this problem.' failed.

Thank you for your help.** This crash report has been saved to disk as /home/cs/matlab_crash_dump.3276-1 **

MATLAB is exiting because of fatal error___

the crash dump file is also attached.

[Mao Cai]

No matter I use libc.so.6 in matlab (under /usr/local/MATLAB/R2017b/sys/os/glnxa64 directory) and use the OS shipped version, the error is same.

Thanks in advance for any hints!

[Mao Cai]

I have just verified the windows edition of Matlab 2017b. It seem to have the similar problem:

Console output and crash file also attached.

.m file is even simpler:

function matSkelFix()

img=imread('H:\image\skel.bmp');
img=bwmorph(img,'skel',Inf);
imwrite(img,'H:\image\skel.s.bmp');
end

It seems that a library is missing for the display of some graphic components. The easiest way to verify that this is not an incomplete installation problem is to reinstall MATLAB to see if the problem still occurs.

[Mao Cai]

Thanks for the tip. I should have installed it twice. Both installations are successful. And, strangely, the xcb does exist:

cs@cs-VirtualBox:/usr/local/MATLAB/R2017b$ find . -name "*xcb*"

./bin/glnxa64/platforms/ libqxcb.so

./bin/glnxa64/xcbglintegrations

./bin/glnxa64/xcbglintegrations/libqxcb-glx-integration.so

[Nate]

This may be a library pathing issue, here is another person who experienced the same error:

Could not find or load the Qt platform plugin "xcb".

The answers on that question may prove useful.

[Mao Cai]

Thanks for the help! But I am sorry to say, even if LD_LIBRARY_PATH is set to the same as 'matlab -e' output, it still crashes. But this time, it is just a simple 'Abnormal termination'

[voxey]

I got same Error, Qt platform xcb plugin in CentOs, how to solve this Error? I complete installed XCB , also its show libraries xcb , but when i run JAR Deployed application , I got Qt platform xcb plugin Error?

[Mao Cai]

My problem is solved by removing libmwcoder_types.so. Please take a try.

[Busy Young]

Could you please post the details of "removing libmwcoder_types.so"
