OutOfBoundException in StorageService.getAllRanges
---------------------------------------------------
Key: CASSANDRA-933
URL: https://issues.apache.org/jira/browse/CASSANDRA-933
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.6
Reporter: gabriele renzi
Priority: Minor
this was seen on 0.6-beta3 but it appears to be in trunk too, given the same
code for getAllRanges. The problem appeared while accessing a bootstraping node
via nodetool, giving the following stacktrace
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1

...
Basically, no test is performed for non-emptyness of the input token list. If
such list should never be empty, I guess this should be explicit in the
interface/javadoc, otherwise I'm attaching a patch & testcase (pretty silly
code, but the test passes :) )
