… `Comparable` interface (#30050) (#30625) Issue Number: #30484 The objects stored in PriorityQueue must implement the Comparable interface or passed into the customized `Comparator`. If we don't do this, run the program in the JDK17 environment will report an exception: ```java Caused by: java.lang.AssertionError: Expect exception msg contains 'query wait timeout', but meet 'java.sql.SQLException: ClassCastException, msg: class org.apache.doris.resource.workloadgroup.QueueToken cannot be cast to class java.lang.Comparable (org.apache.doris.resource.workloadgroup.QueueToken is in unnamed module of loader 'app'; java.lang.Comparable is in module java.base of loader 'bootstrap')' ```
