Chris Hegarty created HADOOP-12760:
--------------------------------------
Summary: sun.misc.Cleaner has moved to a new location in OpenJDK 9
Key: HADOOP-12760
URL: https://issues.apache.org/jira/browse/HADOOP-12760
Project: Hadoop Common
Issue Type: Bug
Reporter: Chris Hegarty
Priority: Minor
This is a heads-up: there are upcoming changes in JDK 9 that will require, at
least, a small update to org.apache.hadoop.crypto.CryptoStreamUtils &
org.apache.hadoop.io.nativeio.NativeIO.
OpenJDK issue no. 8148117: "Move sun.misc.Cleaner to jdk.internal.ref" [1],
will move the Cleaner class from sun.misc to jdk.internal.ref. There is ongoing
discussion about the possibility of providing a public supported API, maybe in
the JDK 9 timeframe, for releasing NIO direct buffer native memory, see the
core-libs-dev mail thread [2]. At the very least CryptoStreamUtils & NativeIO
[3] should be updated to have knowledge of the new location of the JDK Cleaner.
