BugfixDeflater_JDK8252739 causes Java security issues in JDK 11

We are running into issues when running Elasticsearch CI with java security turned on and using JDK11 (only for the ones that contains the jdk bug ).   The errors look like:

java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "accessDeclaredMembers") 

The issue seems to be here:

http://hg.openjdk.java.net/jdk/jdk11/file/1ddf9a99e4ad/src/java.base/share/classes/java/util/zip/Deflater.java#l989

As we now have a subclass that wants to run this code. Note that this code has been removed in JDK12 and above.

We might need to wrap the creation of this object in a doPriviledged Block or find a different solution that does not need to subclass the Deflater class.
