Hi,
I am overriding the query component and creating a custom component. I am
using _responseDocs from org.apache.solr.handler.component.ResponseBuilder
to get the values. I have my component in same package
(org.apache.solr.handler.component) to access the _responseDocs value.
Everything works fine when I run the test for this component but I am
getting the below error when I package the custom component in a jar and
place it in lib directory (inside solr/lib - using basic jetty
configuration).
I assume this is due to the fact that different class loaders load different
class at runtime. Is there a way to resolve this?
