             Summary: StorageService.rebuild() throws RuntimeException when interrupted
                 Key: CASSANDRA-15112
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15112
             Project: Cassandra
          Issue Type: Bug
            Reporter: eBugs in Cloud Systems


Dear Cassandra developers, we are developing a tool to detect exception-related bugs in Java. Our prototype has spotted the following {{throw}} statement whose exception class and error message seem to indicate different error conditions. Since we are not very familiar with Cassandra's internal work flow, could you please help us to verify if this is a bug, i.e., will the callers have trouble handling the exception, and will the users/admins have trouble diagnosing the failure?

 

Version: Cassandra-3.11 (commit: 123113f7b887370a248669ee0db6fdf13df0146e) 

File: CASSANDRA-ROOT/src/java/org/apache/cassandra/service/StorageService.java

Line: 1313

Class: {{RuntimeException}}

Error message: {{"Interrupted while waiting on rebuild streaming"}}

Reason: {{RuntimeException}} is usually used to represent errors in the program logic (think of one of its subclasses, {{NullPointerException}}), while the error message indicates that an interrupt has occurred. Will this mismatch be a problem? For example, will the callers miss the possibility that {{StorageService.rebuild()}} can be interrupted because it does not throw any {{InterruptedException}}? Or, will the callers try to handle other {{RuntimeException}} accidentally (and incorrectly) handle the interrupt?
