Describe the bug
javac crashes when @Getter(lazy=true) with specific content is encountered in the code

To Reproduce

import java.util.function.Predicate;
import java.util.stream.Stream;
import lombok.Getter;

public class Sample {
	@Getter(lazy = true)
	private final String something = Stream.<String>empty()
		.filter(this.contains("test")) // also com.google.common.base.Predicates.alwaysTrue() would trigger the bug
		.skip(true ? 1 : 0)
		.findAny()
		.get();

	private Predicate<String> contains(String s) {
		return (checked -> checked.contains(s));
	}
}

mvn clean compile crashes:

An exception has occurred in the compiler (17.0.8). Please file a bug against the Java compiler via the Java bug reporting page (https://bugreport.java.com) after checking the Bug Database (https://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.

Yes, it is a duplicated and caused by type resolution for arguments. It happens if an initializer contains method arguments with different types. The fix is almost finished.
