Unable to resolve 112.0: missing requirement [112.0] osgi.wiring.package; (&(osgi.wiring.package=org.osgi.framework)(version>=1.8.0))

I am creating a simple Echo service bundle in apache Karaf 3.0.3, I have my Activator class,

package com.company.activator;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class Activator implements BundleActivator {

    private static BundleContext context;

    static BundleContext getContext() {
        return context;
    }

    /*
     * (non-Javadoc)
     *
     * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext)
     */
    public void start(final BundleContext bundleContext) throws Exception {
        Activator.context = bundleContext;
    }

    /*
     * (non-Javadoc)
     *
     * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext)
     */
    public void stop(final BundleContext bundleContext) throws Exception {
        Activator.context = null;
    }

I am able to create the Bundle Via eclipse, with the following Mannifest file

Manifest-Version: 1.0
Private-Package: com.company.activator
Built-By: noushad
Tool: Bnd-0.0.238
Bundle-Name: osgi
Created-By: Apache Maven Bundle Plugin
Build-Jdk: 1.7.0_76
Bundle-Version: 1.0.0

Bundle-ManifestVersion: 2
Bundle-Activator: com.company.activator.Activator
Export-Packages: com.company.echo
Bundle-SymbolicName: com.company.osgi
Import-Package: org.osgi.framework;version="1.8"

Also I have the following POM file

    </build>
</project>

Also my Echo Class

package com.company.echo;

public class Echo {

    public String echo(final String string) {
        return string;
    }
}

I face the following problem(s) when i deploy this application on the karaf 3.0.3

1. Getting the following stack trace when I try to start the bundle

   ERROR: Bundle com.company.osgi [112] Error starting/stopping bundle. (org.osgi.framework.BundleException: Unresolved constraint in bundle com.company.osgi [112]: Unable to resolve 112.0: missing requirement [112.0] osgi.wiring.package; (&(osgi.wiring.package=org.osgi.framework)(version>=1.8.0))) org.osgi.framework.BundleException: Unresolved constraint in bundle com.company.osgi [112]: Unable to resolve 112.0: missing requirement [112.0] osgi.wiring.package; (&(osgi.wiring.package=org.osgi.framework)(version>=1.8.0)) at org.apache.felix.framework.Felix.resolveBundleRevision(Felix.java:3974) at org.apache.felix.framework.Felix.startBundle(Felix.java:2037) at org.apache.felix.framework.Felix.setBundleStartLevel(Felix.java:1483) at org.apache.felix.framework.FrameworkStartLevelImpl.run(FrameworkStartLevelImpl.java:334) at java.lang.Thread.run(Thread.java:745)

Could Some body help me to figure out what the exact problem is.

Thanks in advance..!

I don't think karaf 3 supports OSGi Core R6 (org.osgi.framework package version 1.8). You should try compiling against an other version of the OSGi API.
