Answer 1

The answer is your version of Java is too new for GlassFish. I already answered this here: https://stackoverflow.com/a/49998266/212224

To stop the java.lang.NoClassDefFoundError you need to use a version of Java no higher than 8u151

This is due to a change in internal JDK classes which Grizzly uses for HTTP/2.

GlassFish 5.0 does not have the latest version of Grizzly which is compatible with the latest Java 8 updates. If you are using GlassFish 5.0 and see these errors, you have 2 choices:

1. Downgrade Java to 8u152 or earlier
2. Download the latest GlassFish 5.0.1 nightly, where this should be fixed
