Hi, i am using skywalking-5.0.0-RC2, and encounter a little bug in class AlarmService. Here is the exception:
`java.lang.NullPointerException: null

This bug make server label in Alarm List page unavailable. I have fixed that.But the latested code which i forked doesn't contain that class, so i am a little confused whether i should report things like this?
