             Summary: Migrate away from jsr305 jar
                 Key: HADOOP-16463
                 URL: https://issues.apache.org/jira/browse/HADOOP-16463
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Eric Yang


JSR305 defines several annotations that is prefixed with javax packages.  "javax.annotation.Nullable" is also used by findbugs to suppress code style warnings.  "javax" is a reserved package name according to Oracle license agreement.  Application can not use and ship these dependencies along with a JRE without violating the Oracle licence agreement.  From JDK 9 and newer, [SecurityException|http://blog.anthavio.net/2013/11/how-many-javaxannotation-jars-is-out.html] would be thrown for attempt to run signed code JSR250 + JSR305.

Many developers have look for solution to address [JSR305 annotation issue|https://stackoverflow.com/questions/4963300/which-notnull-java-annotation-should-i-use], but there is no good solution at this time.  One possible solution is to use findbugsExcludeFile.xml to define the actual suppression and this will allow Hadoop to ship without jsr305 dependency.

[Guava jsr305 issue|https://github.com/google/guava/issues/2960]
[HBase jsr305 issue|https://issues.apache.org/jira/browse/HBASE-16321]

This looks like a issue that needs to be addressed if we want to work in newer version of Java environment.
