uses AbstractMap
[ https://issues.apache.org/jira/browse/FLINK-9570?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16509348#comment-16509348 ]

> SQL Client merging environments uses AbstractMap
> ------------------------------------------------
>
> Key: FLINK-9570
> URL: https://issues.apache.org/jira/browse/FLINK-9570
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.5.0
> Reporter: Dominik Wosiński
> Priority: Major
>
> Currently _Environment.merge()_ function looks like below:
>
> {code:java}
> final Environment mergedEnv = new Environment();
> // merge tables
> final Map<String, TableDescriptor> tables = new HashMap<>(env1.getTables());
> mergedEnv.getTables().putAll(env2.getTables());
> mergedEnv.tables = tables;
> {code}
> and no-arg constructor for _Environment_ defaults tables to _Collections.emptyMap()._
> This basically results in calling _putAll_ on _EmptyMap_ which defaults to _AbstractMap_ which always throws _UnsuppoertedOperationException._
