------------------------------

             Summary: hadoop-client-runtime-3.3.0 not properly shading javax.xml.bind
                 Key: HADOOP-17540
                 URL: https://issues.apache.org/jira/browse/HADOOP-17540
             Project: Hadoop Common
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 3.3.0
            Reporter: Lorie


In the file hadoop-client-modules/hadoop-client-runtime/pom.xml, it excludes javax.xml.bind because it says it is part of the SE JDK.  But, this is no longer true in Java 11.  So, when I try to use Guice to inject objects at start up,  I am getting the error

Error injecting constructor, java.lang.NoClassDefFoundError: org/apache/hadoop/shaded/javax/xmlbind/ModuleUtil (wrong name: javax/xml/bind/ModuleUtil)

 
|<exclusions>|
| |<!-- these APIs are a part of the SE JDK -->|
| |<exclusion>|
| |<groupId>javax.xml.bind</groupId>|
| |<artifactId>jaxb-api</artifactId>|
| |</exclusion>|

 

I was able to get past this by using zip to change the position of the ModuleUtil.class inside the META-INF directory.

Before I made any changes:
jar tvf hadoop-client-runtime-3.3.0.jar | grep ModuleUtil*

META-INF/versions/9/javax/xml/bind/ModuleUtil.class
org/apache/hadoop/shaded/javax/xml/bind/ModuleUtil.class

After I modified the jar:

jar tvf hadoop-client-runtime-3.3.0.jar | grep ModuleUtil*

META-INF/versions/9/org/apache/hadoop/shaded/javax/xml/bind/ModuleUtil.class
org/apache/hadoop/shaded/javax/xml/bind/ModuleUtil.class

With the revised jar file, my code started.  I don't know if that is the correct way to fix but it works.
