japicmp post processing script fails with Java 16 (parent pom)

When building the UIMA Java SDK with a Java 16 JDK, we get the following error:

[ERROR] Failed to execute goal com.github.siom79.japicmp:japicmp-maven-plugin:0.14.4:cmp (default) on project uimaj-core: Execution of post-analysis script failed: javax.script.ScriptException: groovy.lang.MissingMethodException: No signature of method: java.lang.String.endsWith() is applicable for argument types: (java.lang.String) values: [_Type] -> [Help 1]

Works with Java 15.

The fix is apparently to force japicmp to use a new Groovy version:

<plugin>
        <groupId>com.github.siom79.japicmp</groupId>
        <artifactId>japicmp-maven-plugin</artifactId>
        <version>0.15.3</version>
        <dependencies>
          <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-jsr223</artifactId>
            <version>2.5.14</version>
          </dependency>
        </dependencies>
      </plugin>
