-----------------------------------
Summary: Memory-mapped files can't be explicitly unmapped
Key: OAK-4274
URL: https://issues.apache.org/jira/browse/OAK-4274
Project: Jackrabbit Oak
Issue Type: Bug
Components: segment-next, segmentmk
Reporter: Francesco Mari
Fix For: 1.6
As described by [this JDK bug|http://bugs.java.com/view_bug.do?bug_id=4724038],
there is no way to explicitly unmap memory mapped files. A memory mapped file
is unmapped only if the corresponding {{MappedByteBuffer}} is garbage collected
by the JVM.
