Suggestion: Setting spring.jmx.default-domain To Unique Values For cas-server-webapp and cas-management-webapp For CAS 5

[William]

Most of the time I will test with cas-server-webapp and cas-management-webapp on the same server which are both Spring Boot applications in CAS 5.  I know this is not typical when deploying these applications as they usually are on different servers.

This results in the following exception:

...

2016-08-19 17:37:08,442 ERROR [org.springframework.boot.SpringApplication] - <Application startup failed>

org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [org.springframework.cloud.context.environment.EnvironmentManager@19480877] with key 'environmentManager'; nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.cloud.context.environment:name=environmentManager,type=EnvironmentManager

        at org.springframework.jmx.export.MBeanExporter.registerBeanNameOrInstance(MBeanExporter.java:625) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]

        at org.springframework.jmx.export.MBeanExporter.registerBeans(MBeanExporter.java:550) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]

...

In src/main/resources/bootstrap.properties in both cas-server-webapp and cas-management-webapp, the spring.jmx.default-domain is not set.  

Could I suggest setting this value uniquely for both applications in bootstrap.properties?  Any reason not to do that?  I can open an issue in GitHub on it.

I can’t think of a good reason to not do that. By all means, create an issue.
