Resolve various build issues surrounding byteman dependencies. I'm honestly
not sure I've done the right things here, but basically consolidate the byteman
and jdbctrace plugin on byteman 1.5.2, which is what we needed for
apache-integration-test module. NOte that current byteman release is 2.2 so
thisis still well behind and now uses some deprecated methods.
Bring Eclipse .classpath up to 4.13 specs.
