问题描述
我在Weblogic中将JWSC ant任务用于Web服务。 （用于构建耳朵）我们在JDK 1.7中使用了12c。那个时候运行良好。但是12c已升级，我们需要使用JDK 1.8。但是之后构建失败。
我遇到以下错误：
:\ata-uje_prod_nettime_4.0.9-ConfigLog\workspace1\nettimej\buildFedexNetoneservice.xml:34: java.lang.LinkageError: loader constraint violation: when resolving method "com.sun.tools.javac.api.JavacTool.getTask(Ljava/io/Writer;Ljavax/tools/JavaFileManager;Ljavax/tools/DiagnosticListener;Ljava/lang/Iterable;Ljava/lang/Iterable;Ljava/lang/Iterable;)Lcom/sun/source/util/JavacTask;" the class loader (instance of java/net/urlclassloader) of the current class,com/bea/util/jam/internal/javadoc/JavadocclassBuilder,and the class loader (instance of sun/misc/Launcher$AppClassLoader) for the method's defining class,com/sun/tools/javac/api/JavacTool,have different Class objects for the type com/sun/source/util/JavacTask used in the signature
