In some situations, e.g. where both a bean class and its superclass have lambdas, Eclipse ECJ will generate synthetic methods to represent the lambda that appear to Weld to be methods that it needs to intercept. This will fail, leading to exceptions like the following during application deployment:

03/01/2025 12:26:19,480 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3) MSC000001: Failed to start service jboss.deployment.unit."temperature-converter-1.0.0.war".WeldStartService: org.jboss.msc.service.StartException in service jboss.deployment.unit."temperature-converter-1.0.0.war".WeldStartService: Failed to start service
