AMQ-9547 - Remove setLength() and usage from RecoverableRandomAccessFile
> KahaDB PageFile can call setLength() on the recovery file which always throws
> an exception
> ------------------------------------------------------------------------------------------
>
> Key: AMQ-9547
> URL: https://issues.apache.org/jira/browse/AMQ-9547
> Project: ActiveMQ Classic
> Issue Type: Bug
> Components: KahaDB
> Affects Versions: 5.18.5, 6.1.3
> Reporter: Christopher L. Shannon
> Assignee: Christopher L. Shannon
> Priority: Major
> Fix For: 6.2.0, 5.18.6, 6.1.4

> Time Spent: 20m
> Remaining Estimate: 0h
>
> There are 3 places in PageFile (part of KahaDB) that call setLength() in
> RecoverableRandomAccessFile. This method was changed in AMQ-5578 so that it
> always throws an exception when called. This method should just be removed
> entirely since it always throws an error and in the places where it is used
> we need to either stop calling it if we can or throw an exception if the
> length is unexpected.
> Currently when KahaDB tries to redo recovery updates, if the file length is
> encountered as 0 it will call this method which leads to throwing an
> exception. This causes the store to detect the error and rebuild the index.
> We should be able to just continue without calling this method and recover.
