Assertion failure in +[NSUndoManager _endTopLevelGroupings],

See original GitHub issue

When I try the demos I get errors like:

This is either after executing:

./mvnw package
java -jar target/lwjgl3-demos.jar

or:

./mvnw package -Dclass=opengl.UniformArrayDemo
java -cp target/lwjgl3-demos.jar org.lwjgl.demo.opengl.UniformArrayDemo
