Resolution

Utilize the 10.1 equivalent GMU 1.8 which should be compliant with JDK11.

The mentioned class sun/misc/BASE64Decoder was removed in jdk 9+ which is utilized in gmu 1.7 and below. So you need to ensure version currency with the GMU tool running the equivalent version to the JDK and Gateway you are running with.
