Cannot rewrite S3Proxy AwsSdkAnonymousTest.java

[gaul]

Describe the bug

I am trying to rewrite S3Proxy's use of the V1 SDK with the V2 SDK. It fails with an error:

[ERROR] The recipe produced an error. Please report this to the recipe author.
[ERROR] Failed to execute goal org.openrewrite.maven:rewrite-maven-plugin:6.19.0:dryRun (default-cli) on project s3proxy: Execution default-cli of goal org.openrewrite.maven:rewrite-maven-plugin:6.19.0:dryRun failed: Error while visiting src/test/java/org/gaul/s3proxy/AwsSdkAnonymousTest.java: java.lang.ClassCastException: class org.openrewrite.java.tree.J$MethodInvocation cannot be cast to class org.openrewrite.java.tree.J$Identifier (org.openrewrite.java.tree.J$MethodInvocation and org.openrewrite.java.tree.J$Identifier are in unnamed module of loader org.codehaus.plexus.classworlds.realm.ClassRealm @15e08615)
