Hi, I'm struggling with the dreaded java.lang.LinkageError. Here's what I'm trying to do. Bundle A consists of a class TestA which is calling a method in class TestB, hosted in Bundle B. As part of the method call, TestA is passing a Solrj class (org.apache.solr.common.SolrInputDocument) to TestB. Here's the pom configuration.
Bundle B pom

As you can see, I'm exporting org.apache.solr.common.*,
org.apache.solr.client and
org.apache.solr.client.solrj package in
bundle B, which is being imported in bundle A.
But I'm getting the following runtime exception.
java.lang.LinkageError: loader constraint violation: loader (instance of
org/apache/felix/framework/ModuleImpl$ModuleClassLoaderJava5) previously
initiated loading for a different type with name
"org/apache/solr/common/SolrInputDocument"
Not sure what I'm missing. I'm using servicemix 4.4.0.
Any pointer will be highly appreciated.
-Thanks,
Shamik
