Migrate to Java 8 (sponsored contribution)
Java >8 includes many helpful features and API additions. Current
phoronix benchmarks indicated a very similar performance. Furthermore,
the fact that Java 18 even works with 1.8.8 contributed to the
decision to move to Java 17 like vanilla Java in 1.19.
This also helps us to learn about the newer features added for our
personal interests. As this is a free project, this motivated us to make
this step.
Nevertheless, many server owners were frustrated about this decision.
Thanks to financial contribution, we revised this decision until Java 8
is end of life or no longer used actively used according to bstats.org

+# About
+
+This contains test resources for the unit tests. The file are extracted from the Minecraft directory with slight
+modifications. The files are found in `$MINECRAFT_HOME$/profilekeys/`, where `$MINECRAFT_HOME$` represents the
+OS-dependent minecraft folder.
+
+**Notable the files in this folder do not contain the private key information. It should be explicitly
+stripped before including it.**
+
+## Minecraft folder
+
+* Windows: `%appdata%\.minecraft`
+* Linux: `/home/username/.minecraft`
+* Mac: `~/Library/Application Support/minecraft`
+
+## Directory structure
+
+* `invalid_wrong_expiration.json`: Changed the expiration date
+* `invalid_wrong_key.json`: Modified public key while keeping the RSA structure valid
+* `invalid_wrong_signature.json`: Changed a character in the public key signature
+* `valid_public_key.json`: Extracted from actual file
+
+## File content
+
+* `expires_at`: Expiration date
+* `key`: Public key from the original file out of `public_key.key`
+* `signature`: Mojang signed signature of this public key

+This contains test resources for the unit tests. Files in this folder include pre-made cryptographic signatures.
+
+## Directory structure
+
+* `valid_signature.json`: Extracted using packet extract from actual authentication
+* `incorrect_nonce.json`: Different nonce token simulating that the server expected a different token than signed
+* `incorrect_salt.json`: Salt sent is different to the content signed by the signature (changed salt field)
+* `incorrect_signature.json`: Changed signature
+
+## File content
+
+* `nonce`: Server generated nonce token
+* `salt`: Client generated random token
+* `signature`: Nonce and salt signed using the client key from `valid_public_key.json`
