RFR: JMC-6358: Build fails due to bugs and errors flagged by SpotBugs

[Alex Macdonald]

Hi,

The following webrev [0] addresses issue JMC-6358 [1], in which builds
using SpotBugs fail due to a number of flagged bugs and errors [2].

These errors appear as of a recent resolved bug [3] to use maven central's
OpenJFX. We are currently using spotbugs-maven-plugin version 3.1.3, which
doesn't have support for JDK 10/11 (introduced in version 3.1.3.1). I've
set up a bunch of branches on Travis CI [4] to test the build using
versions 3.1.3.1 through to 3.1.10 (current release), and the updated
spotbugs plugin does not error. There have been a number of improvements
[5] in the spotbugs plugin since 3.1.3, many of which correspond to JDK 11
support. The proposed one-line patch [0] simply updates the version of the
spotbugs-maven-plugin to 3.1.10.

Thoughts?

Cheers,

Alex
