Hi Till, good pointer. This was in issue with two parallel branches (mine and Tims).
I would rather Opt for Renaming the MBean to TriggeredScraperImplMBean. This should also work, or?

The TriggeredScraperImpl implements the interface "TriggeredScraperMBean". The File "TriggeredScraperImpl.java" contains line 163 "mBeanServer.registerMBean(this, new ObjectName(MX_DOMAIN, "scraper", "scraper"));", which leads to the following exception: > > *09:05:26.915 [main] DEBUG > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl - > Unable to register Scraper as MBean* > *javax.management.NotCompliantMBeanException: MBean class > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl does > not implement DynamicMBean, and neither follows the Standard MBean > conventions (javax.management.NotCompliantMBeanException: Class > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl is not > a JMX compliant Standard MBean) nor the MXBean conventions > (javax.management.NotCompliantMBeanException: > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl: Class > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl is not > a JMX compliant MXBean)* > * at > java.management/com.sun.jmx.mbeanserver.Introspector.checkCompliance(Introspector.java:177)* > * at > java.management/com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.registerMBean(DefaultMBeanServerInterceptor.java:313)* > * at > java.management/com.sun.jmx.mbeanserver.JmxMBeanServer.registerMBean(JmxMBeanServer.java:522)* > * at > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl.<init>(TriggeredScraperImpl.java:163)* > * at > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl.<init>(TriggeredScraperImpl.java:134)* > * at > org.apache.plc4x.java.scraper.triggeredscraper.TriggeredScraperImpl.<init>(TriggeredScraperImpl.java:96)* > * at org.apache.plc4x.logstash.Plc4x.start(Plc4x.java:116)* > * at > org.apache.plc4x.logstash.Plc4xInputTest.testPlc4xInput(Plc4xInputTest.java:51)* > * at > java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native > Method)* > * at > java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)* > * at > java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)** > ....* This means the Standard MBean naming convention is violated. My proposed fix is to refactor the class name from "TriggeredScraperImpl" to "TriggeredScraper" to fulfil the naming conventions. What do you think?
