Steps to Reproduce:
Hide

1. Create and build connector extensions (is not needed to reproduce,
as attached the binary)
2. Upload the connector extension;
3. Create a connection based on the connector extension;
4. Create one integration with a start connector based on a timer with default configuration and a end connector based on the custom connector. You can also directly import the ZIP which is attached
5. Publish integrations.
6. Have a look at the logging of the application pod in Openshift.
7. In logs we see exception.

My Observation:

From code, I observe that json scheme for custom component is not being fetched from class CamelCatalogJsonSchemaResolver.java(Seems new org.apache.camel.catalog package in Camel 2.21.x).

Image Description:
1. syndesis_not_null_for_timer_component.png: json is not-null for timer component.
2. syndesis_null_for_custom_component.png: json is null for custom camel component.
3. syndesis-extraComponents.png: It try to get json scheme from CamelCatalogJSonSchemaResolver.extraComponentsJSonSchema but that too is null.
