「NetBeans 7でのRESTful Webサービスの作成」チュートリアルで例外発生

##問題発生
NetBeans8で[NetBeans 7でのRESTful Webサービスの作成]
(http://www.oracle.com/webfolder/technetwork/jp/obe/java/RESTfulWebservices/RESTfulWebservices.htm) をこなしていると、最後の「RESTful Webサービスのテスト」においてJSON形式でデータを受け取ろうとするとjava.lang.NoClassDefFoundErrorが発生する。
XML形式なら問題無し。

##解決方法
GlassFish内のEclipseLinkが原因らしい。
https://bugs.eclipse.org/bugs/show_bug.cgi?id=463169 にあるようにGlassFish内のEclipseLinkのライブラリを最新のものに置き換えると解決。

置き換えようの最新のEclipseLinkはhttp://www.eclipse.org/eclipselink/#download からOSGi Bundle版をダウンロードする。

- org.eclipse.persistence.antlr.jar
- org.eclipse.persistence.asm.jar
- org.eclipse.persistence.core.jar
- org.eclipse.persistence.dbws.jar
- org.eclipse.persistence.jpa.jar
- org.eclipse.persistence.jpa.jpql.jar
- org.eclipse.persistence.jpa.modelgen.processor.jar
- org.eclipse.persistence.moxy.jar
- org.eclipse.persistence.oracle.jar

念のためorg.eclipse.persistence.dbws.builder.jar も最新のものに置き換えた。
