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.
