LombokValueToRecord results in broken if method references are used

What version of OpenRewrite are you using?

• OpenRewrite v1.2.3
• Maven/Gradle plugin v1.2.3
• rewrite-module v1.2.3

How are you running OpenRewrite?

From the sources of rewrite-migrate-java.

What is the smallest, simplest way to reproduce the problem?

The recipe correctly adapts method invocations to the changed getter naming convention: getTest() -> test(). But it does not do so for method references, i.e. a::getTest remains as it is.

Are you interested in contributing a fix to OpenRewrite?

Yes, I would like to, but could you elaborate on how openrewrite models method references? Is it some kind of member reference?

Correct. There is a J.MemberReference type, which in case it is a reference to a method has a non-null methodType: https://github.com/openrewrite/rewrite/blob/516c70b89ebbb43803d2dd6e0bc2cf31307a80d3/rewrite-java/src/main/java/org/openrewrite/java/tree/J.java#L3454-L3460. This methodType is the type attribution for the method the method reference refers to.

Hope this helps!

Hope this helps!

yes! I will look into it after my vacation.

I tried to implement it, but I encountered an issue. which is demonstrated here:

• https://github.com/openrewrite/rewrite-migrate-java/pull/469

For a member reference a::getTest the field methodType is null. It works however for static methods...

Any ideas @knutwannheden @timtebeek ?
