p6spy makes Tomcat8 will no longer redeploy when in use

Question

Cannot redeploy tomcat when I am using p6spy on top of my Postgres database driver.

It works great until redeploy. When I do a redeploy, I get this error:

javax.management.InstanceAlreadyExistsException: com.p6spy.engine.logging:name=P6LogOptions

Is there a way around this?

Answer 1

You should be able to get around that problem by disabling the JMX functionality in P6Spy. You would do this by setting the following setting in spy.properties.

jmx=false

If you are not using a DataSource (meaning that you have a JDBC URL), then you can also set 'jmx=false' as a URL parameter on the JDBC URL as well.

BTW - This looks like a bug in P6Spy. If you don't mind, please create an issue in the P6Spy GitHub project.
