Thanks for noticing and applying this change @izeye! I do recall seeing issues with

rewrite/rewrite-java/src/main/java/org/openrewrite/java/style/EmptyBlockStyle.java

Lines 28 to 30 in 0805fef

	public class EmptyBlockStyle implements Style {
	@NonNull
	BlockPolicy blockPolicy;

and

rewrite/rewrite-java/src/main/java/org/openrewrite/java/style/OperatorWrapStyle.java

Lines 28 to 33 in 0805fef

	public class OperatorWrapStyle implements Style {
	/**
	* Whether to add a newline for the token at the end of the line.
	*/
	@NonNull
	WrapOption wrapOption;

which are the last two to use our internal @NonNull annotation changed here. Those changes had previously been reverted in 0805fefa. That means we'll likely need to keep a closer eye on this after a merge, which is then perhaps best merged when everyone's back to work next week.
