Description

When compiling via Ant Groovyc task, the compiler generates erroneous Java from the two following files:

B.groovy

class B {
    Map<String, Map<String, Integer[]>> columnsMap = [:]
}

C.java

public class C {
    public void f(B b) {
        System.out.println(b.getColumnsMap());
    }
}

Ant compilation results in many lines with the same error (full log attached):

  [groovyc] /tmp/groovy-generated-2531065055182916850-java-source/B.java:16: ';' expected
  [groovyc] public  java.util.Map<java.lang.String, java.util.Map<java.lang.String, [Ljava.lang.Integer;>> getColumnsMap() { return (java.util.Map<java.lang.String, java.util.Map<java.lang.String, [Ljava.lang.Integer;>>)null;}

Notes:

• if C.java is excluded from build, everything compiles fines.
• Eclipse plug-in compiles code fine too.

And if it's needed, the Ant task:

    <target name="compile2" depends="check_java_version,prepare_libs">
        <mkdir dir="temp_src/classes"/>

        <path id="groovy.class.path">
            <fileset dir="${lib.dir}/groovy" includes="*.jar"/>
        </path>

        <taskdef name="groovyc"
                 classname="org.codehaus.groovy.ant.Groovyc"
                 classpathref="groovy.class.path" />

    </target>
