Java 11: Unable to load JDK7 types (annotations, java.nio.file.Path): no Java7 support added

See original GitHub issue

Might be OK to ignore for now but seeing this warning when running with a jlink’d minimal Java 11 image:

Sep 07, 2019 12:25:42 AM com.fasterxml.jackson.databind.ext.Java7Support <clinit>
WARNING: Unable to load JDK7 types (annotations, java.nio.file.Path): no Java7 support added

On closer inspection it looks like com.fasterxml.jackson.databind.ext.Java7SupportImpl tries to load the annotation java.beans.Transient to detect Java 7 but this doesn’t work on Java 11+ without the full java.desktop module dependency.

Ok, so, for 2.10 I split Java7Support/-Impl into 4 classes; 2 new ones being Java7Handlers/-Impl. J7Support now loads annotation part, and J7Handlers serializer/deserializer for Path type, and only latter will log anything in case of failure. So I think this should work better for J2SE at least. I’ll see if I should change 3.0 a bit as well, to revert merge of annotation access into main part and leave it as extension.

For anyone following, there is: #2744 for Android part – question of Java 11 is little bit different.
