Service Builder generated code fails to compile, compiler claims that methods annotated with @Override do not override anything

• Type: Bug
• Status: Closed
• Resolution: Won't Fix
• Affects Version/s: 6.2.0 CE B1
• Fix Version/s: 6.2.0 CE B1
• Component/s: Core Infrastructure > Service Builder
• Labels: None
• Environment: Java 7 OpenJDK; Oracle Java 7 JDK

How to reproduce:

1. Create a portlet
2. Put this at service.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.1.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_1_0.dtd">
<service-builder package-path="example">
	<author>adam</author>
	<namespace>FailedServiceBuilder</namespace>

	<entity name="Post">
		<column name="postId" type="long" primary="true" />
		
		<column name="title" type="String" />
		<column name="content" type="String" />
	</entity>
</service-builder>

3. run ant build-service

Expected result:

• The classes are compiled, the service jar is generated

Actual result:

• The compilation fails with messages such as

      [javac] 69. ERROR in /home/adam/lib/liferay/liferay-plugins-sdk-6.1.1/portlets/failed-service-builder-portlet/docroot/WEB-INF/service/example/service/PostServiceWrapper.java (at line 74)
