[jira] [Updated] (ARTEMIS-2536) Using artemis-server-osgi can not
load JsonLoader.loadProvider()
[ https://issues.apache.org/jira/browse/ARTEMIS-2536?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Justin Bertram updated ARTEMIS-2536:
------------------------------------
Description:
I have an OSGi project set up. I am using the {{artemis-server-osgi}} bundle. Additionally I have added:
* {{javax.json.javax.json-api}}
* {{org.apache.johnzon.johnzon-core}}
While setting up a cluster environment I get the following exception:
{noformat}
Caused by: javax.json.JsonException: Provider org.glassfish.json.JsonProviderImpl not found

{noformat}
it can easily be reproduced simple by calling {{JsonLoader.createArrayBuilder()}} in a non cluster setup.
This is mainly due to this code in {{JsonLoader}}:
{code:java}
Thread.currentThread().setContextClassLoader(JsonLoader.class.getClassLoader());
{code}
The OSGi loads the Artemis and the Johnzon bundles separately. When {{JsonLoader.class.getClassLoader()}} is called Johnzon is not in this particular classloader.
Something similar we get when we need to load protocol manager factory but there is an alternative to set it manually:
{code:java}
activeMQServer.addProtocolManagerFactory(new MQTTProtocolManagerFactory());
{code}

it can easily be reproduced simple by calling JsonLoader.createArrayBuilder(); in a non cluster setup.
This is mainly due to
Thread.currentThread().setContextClassLoader(JsonLoader.class.getClassLoader());
inside the JsonLoader, as the osgi loads the Artemis bundle and the Johnson separately.
when JsonLoader.class.getClassLoader() is called the Johnson is not in this particular classloader.
Something similar we get when we need to load protocol manager factory but there is an alternative to set it manually:
activeMQServer.addProtocolManagerFactory(new MQTTProtocolManagerFactory());
