Karaf 4.2.1 - error on stopping org.ops4j.pax.jdbc.config/1.3.0

Hi,

with Karaf 4.2.1, during the startup phase I get an exception from
org.ops4j.pax.jdbc.config when this bundle is stopped. This only occurs when
defining more than one datasource configuration. It is not 100%
reproducible, so it could be due to some race condition during startup. When
switching back to pax-jdbc 1.1.0 (in org.apache.karaf.features.cfg AND in
the enterprise feature file), it works correctly.

Below the error message from karaf.log.

Any idea?

Regards,

Jochen

Hi,

answering to my question: it was a bug in pax-jdbc (
https://ops4j1.jira.com/browse/PAXJDBC-133
<https://ops4j1.jira.com/browse/PAXJDBC-133>  ).  Fixed in 1.3.1.

Regards,
Jochen
