Hi @sreuland, can you review this PR?

[sreuland]

sure, this pr is large, can you provide some guidance on where to start or drill down from, etc to understand the change for context?

This PR is actually not that big, it looks big because most of the changes are generated code from testing. We mainly need to focus on the changes in the lib/xdrgen/generators folder, where the dependency on guava has been removed.

Based on this PR, we can generate the changes required for lightsail-network/java-stellar-sdk#525.

ok, that helps, looks good. Are there tests locally in this repo to confirm the generated java code is compiling, no additional warnings/errors?

ok, that could be a follow-on ticket to capture tech debt type. This pr is ready to merge correct?
