java - How do I make a HK2 ServiceLocator use the Singleton service instances from the ServiceLocator that it's bridged from? -

we using using extrasutilities.bridgeservicelocator() inject existing singleton application services created in 1 servicelocator jersey restful web services bridging app servicelocator jersey servicelocator.

however singletons exist in 'outer' locator aren't being used - each of services being created once again when injected jersey services. seems singleton visible within scope of servicelocator, if it's bridged.

is intended behaviour? , if there way change behaviour , have true singleton across bridged servicelocators?

i have extracted issue out set of test classes illustrate point below:

public class bridgedservicetest {   private servicelocator _outerservicelocator;   private servicelocator _innerservicelocator;    @test   public void testbridgedinnerserviceok() throws exception   {     servicelocatorfactory servicelocatorfactory = servicelocatorfactory.getinstance();      _outerservicelocator = servicelocatorfactory.create("outer");     servicelocatorutilities.addclasses(_outerservicelocator, singletonserviceimpl.class);      _innerservicelocator = servicelocatorfactory.create("inner");     extrasutilities.bridgeservicelocator(_innerservicelocator, _outerservicelocator);      final client client1 = new client();     _outerservicelocator.inject(client1);     assertthat(singletonserviceimpl.instancecount.get(), matchers.is(1));     client1.test();      final client client2 = new client();     _innerservicelocator.inject(client2);     // next line fails instance count 2     assertthat(singletonserviceimpl.instancecount.get(), matchers.is(1));     client2.test();   }    @after   public void teardown() throws exception   {     _innerservicelocator.shutdown();     _outerservicelocator.shutdown();   } }  @contract public interface singletonservice {   void fulfil(); }  @service public class singletonserviceimpl implements singletonservice {   public static atomicinteger instancecount = new atomicinteger();    @postconstruct   public void postconstruct()   {     instancecount.incrementandget();   }    @override   public void fulfil()   {     system.out.println("contract fulfilled.");   } }  public class client {   @inject   private singletonservice _singletonservice;    public void test()   {     _singletonservice.fulfil();   }    public singletonservice getsingletonservice()   {     return _singletonservice;   } } 

there bug in servicelocator bridge has been fixed. fix in hk2 2.5.0-b07 or later!
