Description:
Every time build runs setup-java adds a new toolchain element to toolchains.xml. Even if it already exists.

<?xml version="1.0"?>

    I am getting this weird issue as well, and from the logs it seems this file is already 41k lines.

    Resolved Java 17.0.1+12 from tool-cache

  Error: Missing closing element tag end symbol `>`

    The file should be recreated and then grow again; the only problem is if you added custom information to it manually. You'd have to redo that part. However, what you probably could do as a workaround is a run a custom shell step at the end of the job to delete this file and have it re-created again during setup-java execution.

    Linking implementation: this is being addressed by PR #534 (Maven toolchains.xml unexpected growth). Tracking it there — this issue should auto-close when #534 merges.
