TestNG not waiting till my Spring session initialised

I have some sort of following code and if I run it with single test tag xml it works fine. But, when I have multiple tests suites it's simply skips all tests and run last one.

I know that to init Spring takes much time , but how could I wait till my session get init in @BeforeSuite(alwaysRun=true) ?

Note :- Thread.sleep(); also not my solution :(

@BeforeSuite(alwaysRun=true)
    public void contextSetup() throws Exception {
        start = new Date();     
        spContext = createContext();
        importStandardConfiguration(spContext);  
    }

    @BeforeTest(alwaysRun=true)
    @Parameters({"testConfigFile"})
    public void testContextSetUp(String fileName) throws Exception{
        loadTestContext(fileName);
        _skippedTests = new ArrayList<String>();
    }

    @AfterTest
    public void releaseContext() throws GeneralException{
        testContext = null;
        universalMap.clear();
    }

    @AfterSuite
    public void releaseSpContext() throws GeneralException{
        if(spContext!=null)SPFactory.releaseContext(spContext);
        throw new GeneralException("Encountered leaked Context");
    }

@Test(dataProvider="DataFile")
    public void testConnectorImplementation(Map parameter) throws Exception { }

And my TestNG file look like this

<!DOCTYPE suite SYSTEM "http://ift.tt/1ue4P4h" >
<suite name="My Tests Suite" verbose="0">

    <test name="First Test">
        <parameter name="testConfigFile"
            value="config/MyFirstTestConfig.xml" />
        <classes>
            <class name="com.testframework.ConnectorTests">
            </class>
        </classes>
    </test>

<test name="Second Test">
        <parameter name="testConfigFile"
            value="config/MySecondTestConfig.xml" />
        <classes>
            <class name="com.testframework.ConnectorTests">
            </class>
        </classes>
    </test>
</suite>
