Investigate blockers to updating to Kotlin 2.0.0 and later

[jack-h-wang]

User Story

As an RS engineer, I want to remain on current and supported versions of dependencies.

Description/Use Case

RS currently runs Kotlin version 1.9.25. Attempts to update to Kotlin 2.0.0 and later result in compiler failures. There are a number of dependency updates that now require Kotlin 2.0.0 or later. We need to resolve any blockers and update to at minimum Kotlin 2.0.0 in order to update to the current version of many of our dependencies.

Risks/Impacts/Considerations

See the list of dependencies that cannot currently be updated. Note that not all failures are due to this issue; inspect the output of the Build Router step to determine which failures are due to the Kotlin version.

Dev Notes

Update systemProp.kotlinVersion in gradle.properties to a Kotlin 2.x version. Note that compileKotlin will fail due to the presence of several instances of @Suppress("NEW_INFERENCE_NO_INFORMATION_FOR_PARAMETER"). Removing these annotations allows compile to succeed, but causes some tests to fail.

Acceptance Criteria

• Update to Kotlin 2.0.0 or later without any test failures
