Subject [jira] [Created] (HADOOP-11049) javax package system class default is too broad
Date Tue, 02 Sep 2014 20:33:21 GMT
Sangjin Lee created HADOOP-11049:
------------------------------------

             Summary: javax package system class default is too broad
                 Key: HADOOP-11049
                 URL: https://issues.apache.org/jira/browse/HADOOP-11049
             Project: Hadoop Common
          Issue Type: Bug
          Components: util
    Affects Versions: 2.6.0
            Reporter: Sangjin Lee
            Assignee: Sangjin Lee
            Priority: Minor


The system class default defined in ApplicationClassLoader has "javax.". This is too broad.
The intent of the system classes is to exempt classes that are provided by the JDK along with
hadoop and minimally necessary dependencies that are guaranteed to be on the system classpath.
"javax." is too broad for that.

For example, JSR-330 which is part of JavaEE (not JavaSE) has "javax.inject". Packages like
them should not be declared as system classes, as they will result in ClassNotFoundException
if they are needed and present on the user classpath.
