AOP problems with spring + eclipse

[ant]

I'm working on an rich client built on the top of eclipse RCP. I have a very simple beans.xml with only one bean:

<bean id="siteStructureService" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
  <property name="serviceUrl" value="http&#58;//localhost&#58;8090/um-pages-middleware-1.0/ws/SiteStructureService" />
  <property name="serviceInterface" value="com.jcake.um.middleware.api.ISiteStructureService" />
</bean>

If I run the factory as:

	public static void main(String[] args) {
		XmlBeanFactory factory = new XmlBeanFactory(new ClassPathResource("/com/jcake/um/beans.xml")); //$NON-NLS-1$
		ISiteStructureService svc = (ISiteStructureService) factory.getBean("siteStructureService"); //$NON-NLS-1$
		SiteStructureElement siteStructure = svc.getSiteStructure();
		System.out.println(siteStructure);
	}

then everything is just fine. If I try the same from my eclipse app, spring jumps in infinite loop or something like that. The processor's load is about 70%, and the application hangs.

I run the app in debug mode. Below there is where it stops:

[...]

And there is nothing more. The processor load increases to about 70%, my application hangs.

Any ideas what it may be and how to fix it? I really do not know how is it possible that the same code works if I run in as main() and it does such strange thing when I run it from eclipse-rcp plugin...

I am getting something similar with my RCP client (Eclipse reporting an Unhandled event loop exception) whenever I declare the following bean and invoke a db operation even though the invocation does not utilise the transaction manager bean:

<bean id="mytransactionManager"
class="org.springframefork.jdbc.datasource.DataSou rceTransactionManager">
<property name="dataSource">
<ref bean="dataSource"></ref>
</property>
</bean>

I am still investigating the cause but I think it may have to do with the fact that this code is running inside an eclipse plugin.

I've reported the bug, the patch is already in eclipse's bugzilla.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=103918

It helped me, so it should also help you.

The patch did not help. I think the issue I am having relates to the eclipse classloaders and the Spring Application Context.

Thank you so much for your feedback.
