To begin with (and unrelated), instantiating the <code>Application</code> class by yourself does not seem to be its intended use. From what one can read from its <a href="http://cr.openjdk.java.net/~michaelm/7113349/7u4/2/jdk7u-osx/new/src/macosx/classes/com/apple/eawt/Application.java.html" rel="noreferrer">source</a>, you are rather expected to use the static instance returned by <code>getApplication()</code>.

Now let's get to the error Eclipse reports. I've ran into a similar issue recently: <code>Access restriction: The method ... is not API (restriction on required project)</code>. 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 <a href="https://stackoverflow.com/a/22475570/1933494">here</a>, or try Access Rules. Other possible scenarios include:

<ul>
<li>Eclipse wants to keep you from using available packages that are not part of the public Java API (solution <a href="https://stackoverflow.com/a/10642163/1933494">1</a>, <a href="https://stackoverflow.com/a/14646810/1933494">2</a>)</li>
<li>Dependencies are satisfied by multiple sources, versions are conflicting etc. (solution <a href="https://stackoverflow.com/a/2174607/1933494">1</a>, <a href="https://stackoverflow.com/a/1090024/1933494">2</a>, <a href="https://stackoverflow.com/a/15746118/1933494">3</a>)</li>
<li>Eclipse is using a JRE where a JDK is necessary (which might be the case here, from what your errors say; <a href="https://stackoverflow.com/a/20197999/1933494">solution</a>) or JRE/JDK version in project build path is not the right one </li>
</ul>

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.

blocks|key|2732627|text|我也有同样的问题。当我最初在Eclipse中创建java项目时，我指定了JRE+8。当我进入项目的构建路径并编辑JRE系统库时，选择了Java+8执行环境。当我选择使用"Alernate+JRE“(仍然是java8)时，它为我修复了这个错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2732628|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I was having the same problem. When I initially created the java project in Eclipse I specified JRE 8.

This happened to me as well, and the answers given here already were not satisfying, so I did my own research.

<h1>Background: Eclipse access restrictions</h1>

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.

<h1>Problem</h1>

Now, there can be situations, where you want to use public Non-API, like <code>sun.misc</code> (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 <code>javax.smartcardio</code>). In that case, we get this error in Eclipse.

<h1>Solution</h1>

The solution is to change the access restrictions. 

<ul>
<li>Go to the properties of your Java project, 

<ul>
<li>i.e. by selecting "Properties" from the context menu of the project in the "Package Explorer". </li>
</ul></li>
<li>Go to "Java Build Path", tab "Libraries". </li>
<li>Expand the library entry</li>
<li>select 

<ul>
<li>"Access rules", </li>
<li>"Edit..." and </li>
<li>"Add..." a "Resolution: Accessible" with a corresponding rule pattern. 
For me that was "<code>javax/smartcardio/**</code>", for you it might instead be "<code>com/apple/eawt/**</code>".</li>
</ul></li>
</ul>

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:

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

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

Just some tips: the access rules are very similar to the import statement. For me, the access rules I added was "javafx/application/**". Just replace the dot in the import statement with forward slash and that's the rule. Hope that helps.

We had to change our application to build against the JDK 1.8 using Window->Preferences->Java->Installed JREs. However, after changing that, the JRE System Library specified in the Project Explorer was still incorrect. To fix this, right click on "JRE System Library [wrong-jre-here]" and change from Execution environment: to "Workspace Default (yer-default-here)"

We use IBM Rational Application Developer (RAD) and had the same problem.

ErrorMessage: 

Access restriction: The type 'JAXWSProperties' is not API (restriction on required library 'C:\IBM\RAD95\jdk\jre\lib\rt.jar')

Solution:

go to java build path and under Library tab, remove JRE System Library. Then again Add Library --> JRE System Library

I had a little different problem. In Project - Properties - Libraries - JRE library, I had the wrong JRE lib version. Remove and set the actual one, and voila - all <code>Access restriction...</code> warnings are away.

If someone is having this issue only in your CI tool while running maven, what did the trick for me was to explicitly define the execution environment in your <code>MANIFEST.MF</code>.

In my case, I did this by inserting the following line in my OSGi bundle manifest file:

<pre><code>Bundle-RequiredExecutionEnvironment: JavaSE-1.8

What worked for me was adding the access restricted package to the MANIFEST.MF file. In Eclipse, the &quot;Access Restricted&quot; errors showed up in the Problems tab for several files. I just right clicked on each error, clicked &quot;Quick Fix&quot;, and chose &quot;Add '[package]' to imported packages&quot;.

Here is the code:

<pre><code>package mscontroller;

import com.apple.eawt.Application;

public class Main {
 public static void main(String[] args)
 {
 Application app = new Application();
 app.setEnabledAboutMenu(true);

 AMEListener listener = new AMEListener();
 app.addApplicationListener(listener);
 JFrame mainFrame = new JFrame("Application Menu Example");
 mainFrame.setSize(500, 500);
 mainFrame.setVisible(true);
 }
}
</code></pre>

here is the error:
