Version 0.200.0 apparently introduced a build failure for the fabric8 client when building with java sdk version 1.8.

@matteriben that is currently expected as the 200 baseline for sundrio was moved up to java 11. We can do a couple of things:

• change fabric8 client to require building with java 11
• change sundrio to create java 8 compatible jars - this will work until changes like the propsed usage of java logging creep in
• create a .1xx branch of sundrio to produce a release without the change to the java 11 baseline.

I thought that there was nothing critical in Sundrio to be merged in our 6.x branch (currently main/master).

The only thing I'm aware of is a bug fix with unbalanced method prefixing that would be nice to pick up

The only thing I'm aware of is a test case that is currently disabled.
