Failed using ImageJ-Matlab to start ImageJ in headless mode

[rmd13]

Hi, I am using ImageJ-Matlab to start ImageJ2 from matlab by the matlab code

open_imageJ = false; % = true works and shows a Fiji panel, but false does not work
ImageJ(open_imageJ)

The non-headless mode runs OK when open_imageJ = true. .Although it shows a message box saying “cannot find java script engine”, the Fiji panel shows afterwards.

But if change open_imageJ to false, it shows the error after the same message box was shown :

[ERROR] Cannot create plugin: org.scijava.plugins.scripting.javascript.JavaScriptScriptLanguage

Error using ImageJ2 (line 99)
Java exception occurred:
java.lang.NullPointerException
