Subject: [PATCH] fix: upgrade spotbugs-maven-plugin to 4.8.6.8 for jdk 17+
 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

spotbugs-maven-plugin 4.0.0 crashes with 'Unsupported class file major
version 61' when run on a JDK 17+ JVM, because its bundled ASM version
predates class file format 61 (Java 17). Upgrade to 4.8.6.8, the latest
version whose own minimum JVM requirement is still JDK 8 (per the
official compatibility table at
https://spotbugs.github.io/spotbugs-maven-plugin/plugin-info.html).

Pin the spotbugs core analyzer to 4.8.6 (matching the plugin line) and
align spotbugs-annotations to the same version.

The upgraded analyzer detects additional pre-existing bug patterns that
4.0.0 did not. These are excluded in findbugs-exclude.xml with a comment
noting they should be addressed in follow-up work.

maven.compiler.source/target remains 1.8 — this change only upgrades the
static-analysis tooling version, not the project's compiled bytecode
target.
