Problem with OSGI while starting Pepper for the first time

[colan101]

Hello,

I wanted to use Pepper to convert CONLL files into the Annis format. The problem is, that Pepper does not run, because I always get the following error message:

2018-08-07 14:10:36,761 INFO [main] o.c.p.c.PepperStarter [PepperStarter.java:1383] An error occured, while starting Pepper. To get more information on that, please check the log file, which is by default located at 'PEPPER_HOME/pepper_out.log'. You now can exit Pepper or try to find out more about that exception using the Pepper console.

When I try "start-osgi" in debug mode, I get the same error with the following warning:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.eclipse.osgi.framework.internal.core.Framework (file:...pepper/lib/osgi-3.9.1-v20130814-1242.jar) to field java.net.URL.factory
WARNING: Please consider reporting this to the maintainers of org.eclipse.osgi.framework.internal.core.Framework
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

I know a little bit about programming, but not enough to find a solution. So after a few hours of searching the internet I thought maybe you could help me. I'm working on Windows10 and I have 2 Versions of Java installed (Version 9.0.4 and Version 1.8.0_181).

Thanks it advance,
