AppCompiler Error - "java.io.ioException" - help needed:

Hi!

Everyime I use the AppCompiler I got tons of these error blocks (repeats literally many dozens times).

java.io.IOException: Unzulässige Funktion.

at sun.nio.fs.WindowsWatchService$Poller.implRegister(Unknown Source)

at sun.nio.fs.AbstractPoller.processRequests(Unknown Source)

at sun.nio.fs.WindowsWatchService$Poller.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

(Note: "Unzulässige Funktion" translated to English means "improper" or "ineligible function")

Although the executables work, the errors make me nervous, because I don't really know what they refer to and if someday the executables will not work anymore.

Any idea?

I am using Matlab 2017a (v9.2), Compiler v6.4 on a win7 PC.

(I also have installed Curve Fitting Toolbox, Optimization Toolbox and Statistics and Machine Learning Toolbox - but I think I currently do not use any function of these toolboxes)

Greetings

Norman
