The BOM has a pluginManagement section that's a bit misleading since Maven isn't going to do anything with it.
It is also invalid at the moment per the following:
This artifact does not seem to be published anymore. Using the BOM with resolution leads to
[WARNING] The POM for org.infinispan:infinispan-protocol-parser-generator-maven-plugin:jar:10.1.1.Final is missing, no dependency information available
[WARNING] Failed to retrieve plugin descriptor for org.infinispan:infinispan-protocol-parser-generator-maven-plugin:10.1.1.Final: Plugin org.infinispan:infinispan-protocol-parser-generator-maven-plugin:10.1.1.Final or one of its dependencies could not be resolved: Failure to find org.infinispan:infinispan-protocol-parser-generator-maven-plugin:jar:10.1.1.Final in https://repo.spring.io/milestone was cached in the local repository, resolution will not be reattempted until the update interval of spring-milestones has elapsed or updates are forced
