Christopher Tubbs created ACCUMULO-3644:
-------------------------------------------
Summary: [FindBugs] DelegationToken.equals() is not symmetric with
PasswordToken.equals()
Key: ACCUMULO-3644
URL: https://issues.apache.org/jira/browse/ACCUMULO-3644
Project: Accumulo
Issue Type: Sub-task
Components: client
Reporter: Christopher Tubbs
Assignee: Josh Elser
Fix For: 1.7.0
FindBugs at rank 8 warns about DelegationToken overriding PasswordToken, but
doing so in a way that makes {{a.equals(b)}} possibly not the same result as
{{b.equals(a)}} when one of them is a DelegationToken and one of them isn't.
I see two fixes:
# ensure that the entirety of what describes DelegationToken are in the bits
checked by PasswordToken and don't override it
# change PasswordToken so that it doesn't consider subclasses to be equal...
they must also be exactly PasswordToken
