Ivan Smurygin commented on KAFKA-6291:
--------------------------------------

Here is another workaround

>                 Key: KAFKA-6291
>                 URL: https://issues.apache.org/jira/browse/KAFKA-6291
>             Project: Kafka
>          Issue Type: Bug
>          Components: zkclient
>    Affects Versions: 0.11.0.0, 1.0.0
>         Environment: Windows 10 (doesn't reproduce on Linux)
> JDK 8
>            Reporter: Viliam Durina
>            Priority: Major
>
> We created {{EmbeddedZookeeper}} and {{ZkClient}} for various tests using this code:
> {code:java}
>         EmbeddedZookeeper zkServer = new EmbeddedZookeeper();
>         ZkClient zkClient = new ZkClient("127.0.0.1:" + zkServer.port(), 30000, 30000,
ZKStringSerializer$.MODULE$);
>         zkClient.close();
>         zkServer.shutdown();
> {code}
> This works fine on Linux, but on Windows, the {{zkServer.shutdown()}} call fails with
this exception:
> {code}

> My workaround is to comment out the {{zkServer.shutdown()}} call, however this leaves
GBs of files in temp directory.
