> Key: HADOOP-11674
> URL: https://issues.apache.org/jira/browse/HADOOP-11674
> Project: Hadoop Common
> Issue Type: Bug
> Components: io
> Affects Versions: 2.6.0
> Reporter: Sean Busbey
> Assignee: Sean Busbey
> Priority: Critical
> Attachments: HADOOP-11674.1.patch
>
>
> A common optimization in the io classes for Input/Output Streams is to save a
> single length-1 byte array to use in single byte read/write calls.
> CryptoInputStream and CryptoOutputStream both attempt to follow this practice
> but mistakenly mark the array as static. That means that only a single
> instance of each can be present in a JVM safely.
