OpenJDK 64-Bit Server VM Temurin-17.0.10+7 (build 17.0.10+7, mixed mode, sharing) 

If the affected version of Logstash is 7.9 (or earlier), or if it is NOT using the bundled JDK or using the 'no-jdk' version in 7.10 (or higher), please provide the following information:

1. JVM version (java -version)
2. JVM installation source (e.g. from the Operating System's package manager, from source, etc).
3. Value of the LS_JAVA_HOME environment variable if set.

OS version (uname -a if on a Unix-like system):

• Amazon Linux 2

Description of the problem including expected versus actual behavior:

$ cd /usr/share/logstash/bin
$ ./logstash-plugin install logstash-input-kinesis logstash-codec-gzip_lines

Steps to reproduce:

Please include a minimal but complete recreation of the problem,
including (e.g.) pipeline definition(s), settings, locale, etc. The easier
you make for us to reproduce it, the more likely that somebody will take the
time to look at it.

[stevennijhof1990]

We were able to workaround this one by forcing date cleanup prior installing the desired module

command: bash -c " /usr/share/logstash/bin/ruby -S gem cleanup date && bin/logstash-plugin install <module> && bin/logstash -f /usr/share/logstash/pipeline/ "

Note that in our case command is being used since this is part of the docker container config file at which afterwards you'll need to start logstash using command line since you're now using the command parameter

[LukasKucharski1887]

Some news on this, we are facing the same problem, an gem cleanup does not help.

• downloaded from https://www.elastic.co/downloads/past-releases/logstash-8-15-0 [macOS aarch64]
• ./bin/ruby -S gem cleanup date && ./bin/logstash-plugin install logstash-integration-aws
  => same problem as in opening post
  Same from 8.12.0

With a fresh 8.15.0.tgz I get already this:
./bin/ruby -S gem list | grep date
date (3.3.4 java, default: 3.3.3 java)
