Groovy parser fails on assert and colon

[greg-at-moderne]

What version of OpenRewrite are you using?

Current main = 52f563b

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

    @Test
    void assertColon() {
        rewriteRun(
          groovy(
            """
            import java.util.Collection
            
            assert args : "Expecting the OpenWhisk home directory to passed"
            """
          )
        );
    }

when added to one of the Groovy tests fails with:

org.opentest4j.AssertionFailedError: [When parsing and printing the source code back to text without modifications, the printed source didn't match the original source code. This means there is a bug in the parser implementation itself. Please open an issue to report this, providing a sample of the code that generated this error. "file.groovy":

-assert args : "Expecting the OpenWhisk home directory to passed"
+assert assertargs : "Expecting the OpenWhisk home directory to passed"
