Support for JDK 17 (work on it began last week)
Work on JDK17 started last week, please see this commit, which changed the class file major number to 61: https://github.com/openjdk/jdk/commit/6be1f5671eab355c835ca38761ca6e427927bc7f
Unfortunalty I am not able to fork ASM (GitLab says I reached the project limit, even though I have zero projects), so I attached a patch to this issue: jdk17_support.patch
