Without looking further into the details, your thinking sounds reasonable to me. Do you feel in a position to create a PR?

> Hello!
> I would like to get your thoughts on the behavior of {{GroovyMBean}} when handling exceptions.
> I am using Groovy to connect to MBeans written in Java. 
> MBeans may throw checked exceptions or unchecked exceptions. According to Java spec, checked exceptions are wrapped in {{[javax.management.MBeanException|http://docs.oracle.com/javase/7/docs/api/javax/management/MBeanException.html]}} whereas unchecked exceptions are wrapped in {{[javax.management.RuntimeMBeanException|https://docs.oracle.com/javase/7/docs/api/javax/management/RuntimeMBeanException.html]}}. Both the {{RuntimeMBeanException}} and {{MBeanException}} implement a {{getTargetException()}} method that allows you to access the original exception that was thrown in the MBean. 
> When I call an operation on my {{GroovyMBean}} which throws an {{MBeanException}}, the original exception is thrown. This is because the {{GroovyMBean}} implementation extracts the target exception from the {{MBeanException}} (https://github.com/groovy/groovy-core/blob/master/subprojects/groovy-jmx/src/main/java/groovy/util/GroovyMBean.java#L111)
> However, when I call an operation on my {{GroovyMBean}} which throws a {{RuntimeMBeanException}}, the wrapper {{RuntimeMBeanException}} is thrown. This is because the {{GroovyMBean}} implementation does not handle extracting the target exception from the {{RuntimeMBeanException}}. 
> This behavior seems inconsistent to me. I think the {{GroovyMBean}} should extract target exception from {{RuntimeMBeanException}} as well.
