I had this problem because the project facet associated with my project was the wrong java version.

To fix this is I did the following:

Right click on the project and select Properties
Select 'Project Facets' and change version of java to something greater than 1.4.
Click [Apply]

This will rebuild your project and hopefully the error will be resolved.

To begin with  and unrelated   instantiating the Application class by yourself does not seem to be its intended use  From what one can read from its source  you are rather expected to use the static instance returned by getApplication     Now let s get to the error Eclipse reports  I ve ran into a similar issue recently  Access restriction  The method     is not API  restriction on required project   I called the method in question as a method of an object which inherited that method from a super class  All I had to do was to add the package the super class was in to the packages imported by my plugin   However  there is a lot of different causes for errors based on  restriction on required project library   Similar to the problem described above  the type you are using might have dependencies to packages that are not exported by the library or might not be exported itself  In that case you can try to track down the missing packages and export them my yourself  as suggested here  or try Access Rules  Other possible scenarios include    Eclipse wants to keep you from using available packages that are not part of the public Java API  solution 1  2  Dependencies are satisfied by multiple sources  versions are conflicting etc   solution 1  2  3  Eclipse is using a JRE where a JDK is necessary  which might be the case here  from what your errors say  solution  or JRE JDK version in project build path is not the right one    This ended up as more like a medley of restriction-related issues than an actual answer  But since restriction on required projects is such a versatile error to be reported  the perfect recipe is probably still to be found

This happened to me as well  and the answers given here already were not satisfying  so I did my own research   Background  Eclipse access restrictions  Eclipse has a mechanism called access restrictions to prevent you from accidentally using classes which Eclipse thinks are not part of the public API  Usually  Eclipse is right about that  in both senses  We usually do not want to use something which is not part of the public API  And Eclipse is usually right about what is and what isn t part of the public API   Problem  Now  there can be situations  where you want to use public Non-API  like sun misc  you shouldn t  unless you know what you re doing   And there can be situations  where Eclipse is not really right  that s what happened to me  I just wanted to use javax smartcardio   In that case  we get this error in Eclipse   Solution  The solution is to change the access restrictions     Go to the properties of your Java project       i e  by selecting  Properties  from the context menu of the project in the  Package Explorer     Go to  Java Build Path   tab  Libraries    Expand the library entry select     Access rules     Edit     and   Add     a  Resolution  Accessible  with a corresponding rule pattern   For me that was  javax smartcardio      for you it might instead be  com apple eawt
