Eric Yang created HADOOP-16463:
----------------------------------
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.
