Hello all,


Can you help me to understand a few options in Eclipse please. I read all the web and help content but I never find a good response for understand.

There is 2 options in : ECLIPSE > windows > preferences > Java > Compiler > Errors/Warnings > Deprecated and restricted API :

- Forbidden reference (access rules)
- Discouraged reference (access rules)


Can you tell me who fix the forbidden and Discouraged reference and where is implementing ?

Where is the access rules ?


Great thank for you and my knowledge of eclipse

When a jar is added into the build path, one can add these access restrictions to some of the packages or classes in the jar. If you are doing PDE development, PDE will add these automatically depending upon the exported packages from the plugin.

You can add it yourselves from the build page. Eclipse automatically adds this for the classes from the JRE's library. The internal classes shouldn't be exposed to users and hence this helps.
