Re: [tycho-user] Problem with Tycho 1.7.0 / JUnit 5 / Java 11

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

You could try packagin jar (with proper dependencies inside pom), a 
suitable classloader would be for example the 
"this.getClass().getClassloader()" but that might depend on your overall 
needs. You can also try set the context-classloader but on the long term 
it might be required that xtext uses proper loading mechanisms.

In general, all code that relies on "a default global classloader" is 
subject to fail in several environments (applet, J2EE, Web...), not only 
OSGi.
