Description

I am using 1.4.1.SNAPSHOT-r951313.

Component "Item":

<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.osgi.org/xmlns/scr/v1.1.0 http://www.osgi.org/xmlns/scr/v1.1.0">
<implementation class="mycompany.impl.MyItemImpl"/>
<reference interface="mycompany.ItemRegister" bind="setItemRegister" policy="dynamic"/>
<service>
<provide interface="mycompany.Item"/>
</service>
</scr:component>

Component "ItemRegister":

<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.osgi.org/xmlns/scr/v1.1.0 http://www.osgi.org/xmlns/scr/v1.1.0">
<implementation class="mycompany.impl.MyItemRegisterImpl"/>
<reference interface="mycompany.Item" bind="addItem" unbind="removeItem" cardinality="0..n" policy="dynamic"/>
<service>
<provide interface="mycompany.ItemRegister"/>
</service>
</scr:component>

Both components reside in the same bundle. On bundle startup I am getting:

java.lang.IllegalStateException: ServiceFactory.getService() resulted in a cycle.

Sure, there is a cycle but this cycle can be resolved as one of the cardinalities is 0..n. If I manually scr disable the component "Item" and enable it again, then all is OK. Also, if XML definition of the "Item" component is being read later than that of component "ItemRegister", then bundle reloading runs OK. But not on the framework startup.
