Quarkus 1.7.4 uses Infinispan protostream. It uses Infinispan protostream-4.3.3.Final-redhat-00002.jar as the productized version of Infinispan protostream. But upstream bits of protobuf-java:3.12.2 and javassist:3.26.0-GA have been found in the protostream jar. Can you check this jar and provide a productized version with these issues resolved? Once the issue is fixed in productized Infinispan jar, we can use that version into Red Hat build of Quarkus.
