Re: [eclipse-dev] Fwd: Uses Conflict
|
I think you should post that question to the Equinox mailing list.
IIRC javax.annotation is provided by the JRE as of Java 1.7 and we
removed the javax.annotation bundle from Eclipse. To remain compatible
Equinox is reexporting the JRE bundle with the 1.2 version. This was
supposed to work without issues but the Equinox people might fill in
the details why is is causing issues for you.
Best regards, Lars
