Description

In a blueprint application importing spring context with custom namespace using aries blueprint-spring integration does not wait for custom namespace.

For example 

with this blueprint context

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:security="http://www.springframework.org/schema/security" xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0         http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd         http://www.springframework.org/schema/beans                         http://www.springframework.org/schema/beans/spring-beans.xsd" default-activation="eager" default-availability="mandatory">
 <spring:import resource="classpath:spring/security.xml" /></blueprint>

importing this spring context

<b:beans xmlns="http://www.springframework.org/schema/security"<b:beans xmlns="http://www.springframework.org/schema/security"  xmlns:b="http://www.springframework.org/schema/beans"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/security https://www.springframework.org/schema/security/spring-security.xsd">
 <http />  <b:bean class="org.springframework.security.crypto.password.NoOpPasswordEncoder"/>
 <user-service> <user name="user" password="password" authorities="ROLE_USER" /> </user-service>
</b:beans>

fails with this stacktrace:

A workaround is to define beans in custom namespace inside the blueprint context, then aries is waiting for custom namespace handler.
