Hi,

I’ve started testing what Logstash (7.3.0) can do and I’m having a problem with the File input plugin‘s “read mode.” It fails on gzip'd files. The problem has been reported before, e.g. here:

> [@Does Logstash (7.0.1) support gzip file input?](https://discuss.elastic.co/t/does-logstash-7-0-1-support-gzip-file-input/181862/6):

Apparently, the read mode part of the plugin is not compatible with Java \>8. That user solved the problem by installing Java 8. My problem is, I am running Elastic’s official `logstash-oss` docker image, which means I cannot downgrade the JVM (unless I build a custom image based on the official one).

Does anyone have an idea or have you encountered this before? Would [GitHub - elastic/logstash: Logstash - transport and process your logs, events, or other data](https://github.com/elastic/logstash/) be the appropriate repository to file a bug report?

Thanks,

Markus

For the record, this is Logstash’s output:

```auto

    (rest of stack trace removed)

```

And the relevant part of my pipeline configuration looks like this:

```auto
file {
    path => ["/var/log/apache2/*-error.log.*.gz"]
    type => "apache_error"
    mode => "read"
    file_completed_action => "log"
    file_completed_log_path => "/dev/null"
}

```

There is already an [issue](https://github.com/logstash-plugins/logstash-input-file/issues/243) for this.
