Applied fixes from a full security/bug audit (per-finding detail in the
maintainer's audit report): dupe/exploit/injection/thread-safety and
input-validation fixes as applicable to this plugin, plus build-portability
fixes (JDK path / dependency pins / path casing) where present.
Added GPL-3.0 LICENSE.
