------------------------------------
Summary: Unmap before resizing
Key: KAFKA-1008
URL: https://issues.apache.org/jira/browse/KAFKA-1008
Project: Kafka
Issue Type: Bug
Components: core, log
Affects Versions: 0.8
Environment: Windows, Linux, Mac OS
Reporter: Elizabeth Wei
Assignee: Jay Kreps
Fix For: 0.8
While I was studying how MappedByteBuffer works, I saw a sharing runtime
exception on Windows. I applied what I learned to generate a patch which uses
an internal open JDK API to solve this problem.
Following Jay's advice, I made a helper method called tryUnmap().
