spring-boot-dependencies contains unwanted dependency management

[wilkinsona]

It's being inherited from log4j-bom. In 3.2.x (Log4j 2.21), it's contributing management for the following dependencies:

• biz.aQute.bnd:biz.aQute.bnd.annotation:6.4.1
• com.github.spotbugs:spotbugs-annotations:4.7.3
• org.osgi:osgi.annotation:8.1.0
• org.osgi:org.osgi.annotation.bundle:2.0.0
• org.apache.maven.plugin-tools:maven-plugin-annotations:3.9.0

In 3.3.x (Log4j 2.23), it's the following:

• biz.aQute.bnd:biz.aQute.bnd.annotation:7.0.0
• com.github.spotbugs:spotbugs-annotations:4.8.3
• org.jspecify:jspecify:0.3.0
• org.osgi:osgi.annotation:8.1.0
• org.osgi:org.osgi.annotation.bundle:2.0.0
• org.osgi:org.osgi.annotation.versioning:1.1.2
• org.apache.maven.plugin-tools:maven-plugin-annotations:3.10.2

In 3.4.x (Log4j 2.24), it's the following:

• biz.aQute.bnd:biz.aQute.bnd.annotation:7.0.0
• com.github.spotbugs:spotbugs-annotations:4.8.6
• org.jspecify:jspecify:1.0.0
• org.osgi:osgi.annotation:8.1.0
• org.osgi:org.osgi.annotation.bundle:2.0.0
• org.osgi:org.osgi.annotation.versioning:1.1.2
• org.apache.maven.plugin-tools:maven-plugin-annotations:3.13.1

I've opened apache/logging-log4j2#3066 to see if the bom can be improved to remove this unwanted dependency management. In the meantime, we may want to move away from using it.

It's not just Log4j2's bom that is problematic. A prototype for #42523 has found the following problems in 3.2.x:
