My bad, I had a separate library for Fuseki 1 on the list and ahead of

Hi Erich, thanks for letting us know.
For the record, in case this style of issue which might occur with other
mixes of jena2, jena3 jars:
Exception in thread "main" java.lang.NoSuchMethodError:
org.apache.jena.atlas.lib.Cache.getIfPresent
At Jena 3.0.0 there were some changes to Jena's own library code.
1/ Caching now uses Google Guava - there is a shaded version in
jena-shaded-guava to avoid version issues.
2/ Some of the library code has been migrated to jena-base
so here jena-core v3 code is run, and it now uses the library caching
code. It is looking for org.apache.jena.atlas.lib.Cache. But
Cache.getIfPresent is a new operation for Jena 3, not in the Jena2
lib.Cache (in jena-arq). Old jena-arq has lib.Cache so it's not a
ClassNotFoundException or NoClassDefFoundError, but a NoSuchMethodError.
It found an old class, it didn't have the method.

NoSuchMethodError is usually indicative of a malformed class path
You likely have a mix of Jena 2.x and 3.x present on your class path so I
would first check your dependency tree carefully
