Uwe Schindler commented on LUCENE-9517:
---------------------------------------
Here is a PR not trying to subclass Deflater, whcih was causing this bug:
https://github.com/apache/lucene-solr/pull/1850
The idea is to ust provide a patch for the setDictionary method, provided by a
functional interface. In non-buggy JVMs it points dircetly to the corresponding
Deflater method, otherwise it provides the workaround using the arraycopy and a
scratchBuffer.
This also allowed to put setDictionary on the forbiddenapis list.

> Key: LUCENE-9517
> URL: https://issues.apache.org/jira/browse/LUCENE-9517
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Ignacio Vera
> Assignee: Uwe Schindler
> Priority: Major
> Time Spent: 3h
> Remaining Estimate: 0h
>
> 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:
>
>
> {code:java}
> java.security.AccessControlException: access denied
> ("java.lang.RuntimePermission" "accessDeclaredMembers") {code}
>
> 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.
