I'm looking for tools or methods to identify potential issues with my code when I switch to new versions of Java. Specifically, I want to check for:
* Usage of methods that are going to be deprecated in future releases
* Methods that have already been removed in upcoming versions
* Any code that might conflict with Valhalla features, like using 'new Long(5)'.
Does anyone have suggestions or insights on how to uncover these potential pitfalls?

A lot of folks are recommending OpenRewrite, but honestly, I typically just compile with the newer Java versions. Unless something is officially marked deprecated, I tend to avoid making unnecessary code changes. If some legacy code is functioning well, like using an anonymous class instead of a lambda, then I'll only update it if I'm already changing that section for something else.
