I'm looking for tools or strategies to help me identify code that may cause problems when I upgrade to newer versions of Java. Specifically, I want to be alerted about: * Deprecated methods that will be removed in future Java versions. * Methods that have already been removed in upcoming versions. * Any potential issues related to Valhalla, like using `new Long(5)`. Any recommendations or advice would be greatly appreciated!

Honestly, the best tool is just the compiler for the version you're upgrading to. Use that, and you'll get warnings and errors related to any changes or deprecations.
One of the simplest ways to catch potential problems is by compiling your code with deprecation warnings enabled on the current JDK. For instance, using `new Long(long)` is deprecated, so you'll be flagged for that automatically.
A lot of developers find tools like OpenRewrite really helpful. But personally, I usually just compile my code with the newer Java version. I don't typically change code unless it's clearly deprecated. If something's working — like using anonymous classes instead of lambdas — I leave it unless I'm already making other updates.
