Lombok: [BUG] SneakyThrows doesn't work with JDK 15

[rdwallis]

Describe the bug
When compiling with javac, I get the following warning:

error: Error during the transformation of 'foo.bar.SomeClass'; post-compiler 'lombok.bytecode.SneakyThrowsRemover' caused an exception: java.lang.IllegalArgumentException: Unsupported class file major version 59

To Reproduce

// Test.java
import lombok.SneakyThrows;
import java.io.IOException;

public class Test {

    @SneakyThrows
    public void testMethod() {
      throw new IOException();
    }

}

Run javac -cp lombok-1.18.12.jar Test.java observe output:

error: Error during the transformation of 'Test'; post-compiler 'lombok.bytecode.SneakyThrowsRemover' caused an exception: java.lang.IllegalArgumentException: Unsupported class file major version 59

There already is a PR (https://github.com/rzwitserloot/lombok.patcher/pull/6) that might fix this issue.

I ended up by just not using SneakyThrows, and it works fine now.

It isn't possible to remove them all in huge project :)

I tested using the latest edge build today (https://projectlombok.org/download-edge), and this issue is still present there.

Thank you everyone on the Lombok Team. This appears to be fixed in Lombok 1.18.14
