What is the status of JSR 305?

I have seen the question JSR305 vs. JSR308 (Java Type Anotations) - Which is going to be the standard? and I understand the difference between JSR 308 and JSR 305.

I also understand that, at this time, 308 is slated for Java 7, and 305 is not, and I am curious about the overall status of 305.

Specifically, I am using Google Collections and JSR-305 in some of my projects (in a similar manner to what one of the Guice best practices advocates) and was wondering if there is a more "future direction"-friendly approach I should be using instead. I am planning to also ask about this on the JSR-305 group, but that group does not have much activity and I was just wondering if anyone here had any more info.

As described in this answer, JSR-305 proposes new annotations such as @NonNull, while JSR-308 proposes allowing annotations in new places such as on generic declarations.

Quoting JSR 308 page:

…this document does not propose any annotations, merely specifying where they can appear in Java code.

JSR 308 (annotations in new places) is included in java 8 under JEP 104.

As of 2017, JSR 305 (new annotations) continues to carry official status of “Dormant”. A question about it's status in the google group has been unanswered since 2010.

There is a reference implementation of the JSR-305 annotations here which is used by many projects, including guava. With maven you can use the JSR-305 reference implementation by adding this to your pom:

<dependency>     <groupId>com.google.code.findbugs</groupId>     <artifactId>jsr305</artifactId>     <version>3.0.0</version> </dependency>
