latest graviton machine types like `*8g` are not currently supported.

Upcoming End-of-Support

• I acknowledge the upcoming end-of-support for AWS SDK for Java v1 was announced, and migration to AWS SDK for Java v2 is recommended.

Describe the bug

The latest graviton machine types like families c8g and m8g are not currently supported. The last machine type additions were the R8g family:

aws-sdk-java/aws-java-sdk-ec2/src/main/java/com/amazonaws/services/ec2/model/InstanceType.java

Lines 830 to 841 in 9197e60

	R8gMedium("r8g.medium"),
	R8gLarge("r8g.large"),
	R8gXlarge("r8g.xlarge"),
	R8g2xlarge("r8g.2xlarge"),
	R8g4xlarge("r8g.4xlarge"),
	R8g8xlarge("r8g.8xlarge"),
	R8g12xlarge("r8g.12xlarge"),
	R8g16xlarge("r8g.16xlarge"),
	R8g24xlarge("r8g.24xlarge"),
	R8g48xlarge("r8g.48xlarge"),
	R8gMetal24xl("r8g.metal-24xl"),
	R8gMetal48xl("r8g.metal-48xl"),

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

The SDK is kept in match step with allowed instance types in AWS until the EOL date.

Current Behavior

Use the latest https://plugins.jenkins.io/ec2/ version in Jenkins and request a c8g or m8g instance type. It will throw and error like this:

Failed to run script file:/usr/local/opt/shared-data/builder/jenkins_home/init.groovy.d/d_ec2_plugin.groovy
java.lang.IllegalArgumentException: Cannot create enum from m8g.medium value!

Reproduction Steps

Use the latest https://plugins.jenkins.io/ec2/ version in Jenkins and request a c8g or m8g instance type. It will throw and error like this:

Failed to run script file:/usr/local/opt/shared-data/builder/jenkins_home/init.groovy.d/d_ec2_plugin.groovy
java.lang.IllegalArgumentException: Cannot create enum from m8g.medium value!

Possible Solution

Can aws/aws-sdk-java-v2@91d3531 be backported from v2->v1?

Additional Information/Context

The https://github.com/jenkinsci/ec2-plugin supports only the v1 sdk currently via the https://github.com/jenkinsci/aws-java-sdk-plugin . Doing this backport would allow time for the aws-java-sdk-plugin be be updated to v2 iof the aws-sdk-java for Jenkins users which is underway in jenkinsci/ec2-plugin#1021 .

Hi @danbf,

This falls under the service updates that the Java SDK v1 will not receive anymore after Maintenance phase has started.

To get unblocked, you can use the Instance Type String setter - .withInstanceType("c8g.medium").

Expected Behavior
The SDK is kept in match step with allowed instance types in AWS until the EOL date.

Please note that this is should not be the expected behavior, for any service and not only ec2. Once a SDK has entered Maintenance Mode it will not receive service API updates or new regions, it will only get critical bug fixes and security issue updates. This is mentioned in the end-of-support announcement and also in our Maintenance Policy.
