Could not find implementation of liquibase.logging.Logger on trunk

I’m using the version from trunk, spring and jboss as.

I observed the same exception:

Liquibase: 2.0-rc5.
JBoss 6.0M4

On the other hand on the Glassfish 3.0.1 exception is not thrown. But Glassfish uses JUL as a logging framework, JBoss Log4j.

I was trying to understand how Liquibase loads logger, but ServiceLocator class seems to be magic :frowning: I hope that the issue will be solved by author in the next release.

It is probably an issue with how the jboss classloader works.  I made some fixes earlier, but if you think that ServiceLocator is magic, you should see app server classloaders  :slight_smile:

I’ll look into it, thanks for pointing it out.

I made some changes for the upcoming RC6, could you test it out when it comes out?

Hi Nathan

Thank you for your support. I checked RC6 version and the exception is still thrown:

Are there any news about this bug? I’m still using an old version built by me, because of this bug.

I filled the JIRA issue (please vote for it):
http://liquibase.jira.com/browse/CORE-789

I hope that Nathan will take care of the bug :-).

It’s on my list for the next release.  Will hopefully get to it soon

Hi Nathan,

are there any updates on the issue yet? We are using 2.0.5 in a Tomcat OSGi environment and also have the “liquibase.exception.ServiceNotFoundException: Could not find implementation of liquibase.logging.Logger” exception now.

Thanks, Robert
