Robert Munteanu created GERONIMO-6560:
-----------------------------------------
Summary: JSON spec jar is not able to load provider in an OSGi
environment
Key: GERONIMO-6560
URL: https://issues.apache.org/jira/browse/GERONIMO-6560
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Reporter: Robert Munteanu
I am trying to use org.apache.geronimo.specs:geronimo-json_1.0_spec:1.0-alpha-1
together with Apache Johnzon in a minimal OSGi environment ( see
https://lists.apache.org/thread.html/52ecda6f7b859fa9cdd4d9fb64d6f7a3b54f29f971e5536e844d9150@%3Cdev.johnzon.apache.org%3E
for more details ).
Looking at the manifest of the JSON spec I can see it has no way of loading
classes from another jar, and it fails at runtime:
