Documented Java version requirement is 8, but release requires 11

[WilliamNoad]

Describe the bug The documentation describes the minimum Java version as 8, however releases 2.0.2, 2.0.3 and 2.0.4 have been built using version 11.

My operational environments are limited to running Java 8 for the time being, requiring me to manually downgrade to release 2.0.0 before being able to run the tool.

To Reproduce

1. Create an AWS EC2 instance (e.g. t3.micro) running the current image of Amazon Linux 2.
2. Install the java-1.8.0-openjdk-devel package.
3. Execute the bin\install.sh script and following the onscreen instructions.
4. Run the okta-aws command line e.g. okta-aws default sts get-caller-identity

Expected behavior The expected result is that the command requests the user credentials.

The actual response is:

$ okta-aws default sts get-caller-identity

Additional context This traceback was from using release 2.0.2, however I have tested it with the same failure mode for all releases to 2.0.4.

Really hope this can be resolved. Is there any specific feature in Java 11 being used?

[elice02]

Same problem. Getting CLI access via Okta is very quickly turning into nightmare for me. It's all so hacky and non-functional.

[mraible]

@elice02 This is a community-supported project that no one from Okta works on. Please be kind to the maintainers as they're likely doing this in their free time.

I did some additional digging myself, and noticed that the driver behind the move from Java 8 to Java 11 appear to be the use of the OpenJfx components. These libraries are only available for Java 11 and Java 13.

I haven't been able to determine what part of the Okta AWS tool is making use of these libraries, yet, but as this looks to be a primarily CLI based tool, the inclusion of GUI components seems a little odd to me.
