Structural Replace script to rename class renames class and deletes file content

I'd like to rename all classes that extend Spring's JUnit helper classes from `xxxTest` to `xxxIT`.

For instance, if I have

@SpringJUnitConfig(locations="...")
@Transactional
public abstract class AbstractBaseTest extends AbstractTransactionalJUnit4SpringContextTests {

@Autowired
private SomeInjection someInjection;
// more code elided
}

after running the replace I would have

        @SpringJUnitConfig(locations="...")
        @Transactional
        public abstract class AbstractBaseIT extends AbstractTransactionalJUnit4SpringContextTests {

        @Autowired
        private SomeInjection someInjection;
        // more code elided
        }

And the same would happen for all the classes that extend this base class.

To do this I've come up with the following template:

<replaceConfiguration name="Misnamed Integration Test" text="class $Class$ {}" recursive="false" caseInsensitive="true" type="JAVA" pattern_context="default" reformatAccordingToStyle="false" shortenFQN="false" replacement="class $NewName$ {}">
<constraint name="__context__" within="" contains="" />
<constraint name="Class" script="&quot;if (__context__.interface || __context__.enum) {&#10;    return false&#10;}&#10;def p = __context__.getSuperClass()&#10;while (p != null) {&#10;    println(&quot;parent: &quot; + p)&#10;    if (p.getName().endsWith(&quot;JUnit4SpringContextTests&quot;))&#10;        return true;&#10;    p = p.getSuperClass()&#10;}&#10;return false&#10;&quot;" regexp="\b(.*)((?:Integration)?Test)(.*)\b" target="true" within="" contains="" />
<variableDefinition name="NewName" script="&quot;__context__.name.replaceAll(&quot;((?:Integration)?Test)&quot;, &quot;IT&quot;)&quot;" />
</replaceConfiguration>

The problem is, the replacement produces the following:

class AbstractBaseIT {}

That's it. It strips all the annotations, the modifiers, the extends and implements, as well as the entire contents of the class.

The find part works fine. It's correctly identifying all the classes that should be integration tests.

How do I get the replace to just change the name and not the rest?

UPDATE:

I got closer with the following:

<replaceConfiguration name="Misnamed Integration Test" text="class $Class$ {}" recursive="false" caseInsensitive="true" type="JAVA" pattern_context="default" reformatAccordingToStyle="false" shortenFQN="false" replacement="class $NewName$ {}">
<constraint name="__context__" within="" contains="" />
<constraint name="Class" script="&quot;if (__context__.interface || __context__.enum) {&#10;    return false&#10;}&#10;println(&quot;inital context: &quot; + __context__)&#10;def p = __context__.getSuperClass()&#10;while (p != null) {&#10;    if (p.getName().endsWith(&quot;JUnit4SpringContextTests&quot;))&#10;        return true;&#10;    p = p.getSuperClass()&#10;}&#10;return false&#10;&quot;" regexp="\b(.*)((?:Integration)?Test)(.*)\b" target="true" within="" contains="" />
<variableDefinition name="NewName" script="&quot;__context__.setName( __context__.name.replaceAll(&quot;((?:Integration)Test)&quot;, &quot;IT&quot;))&#10;__context__.text&quot;" />
</replaceConfiguration>

which, while admittedly still wrong, is closer, but throws the following exception:
