Many thanks [~paulk], I retested the above example on snapshots (3.0.0 and 2.5.3), it works ok now.
Closing this issue.

>                 Key: GROOVY-8835
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8835
>             Project: Groovy
>          Issue Type: Bug
>          Components: Groovy Console, Swing
>    Affects Versions: 2.5.2
>            Reporter: Anton Pryamostanov
>            Assignee: Paul King
>            Priority: Minor
>              Labels: inspect
>             Fix For: 3.0.0-alpha-4, 2.5.3
>

> Consider the following example:
> {code:java}
> package groovy
> import groovy.inspect.swingui.AstNodeToScriptVisitor
> import org.codehaus.groovy.ast.expr.EmptyExpression
> import org.codehaus.groovy.ast.tools.GeneralUtils
> class SandBox {
>     static void main(String[] args) {
>         new SandBox().someMethod()
>     }
>     void someMethod() {
>         StringWriter stringWriter = new StringWriter()
>         GeneralUtils.declS(GeneralUtils.varX("someVariableName"), new EmptyExpression()).visit(new AstNodeToScriptVisitor(stringWriter))
>         System.out.println("Output: "+stringWriter.getBuffer().toString().replace("\$", ""))
>     }
> }
> {code}
> Actual result:
> {code}
> Output: java.lang.Object someVariableName = 
> {code}
> Expected result:
> {code}
> Output: java.lang.Object someVariableName
> {code}
> When DeclarationExpression (or possibly other BinaryExpression) is initialized with EmptyExpression as "right" expression, *AstNodeToScriptVisitor* should not output the token ("=" in this example), as there is no corresponding expression printed after the token.
