ImageJ cannot load the scripts

Hi

When launching ImageJ from MATLAB I get the errors bellow telling me that some scripts cannot be loaded. However I checked the paths and the files are there.
Tjh IJM and MIJ objects are created though and they work.

I have the following setup:
OsX sierra
Java 1.8.0_40-b25 (as mentioned in the wiki)
MATLAB 2016b

```

```

Start at net.imagej.matlab.ImageJMATLAB.launch and the start methods in the stack trace, then follow initialization into org.scijava.script.ScriptFinder and DefaultScriptService. Reproduce the reported MATLAB 2016b, Java 1.8, and macOS setup, and compare the JavaScript engine and file-opening failures. Done means ImageJ starts from MATLAB without the reported script-loading errors.
