Symptoms

When I launch SQL DEVELOPER, I get in the Logging Page an error message:

error 108
o.jdbc.driver.OracleDriver
Error while registering Oracle JDBC Diagnosability MBean.

 

In Debug mode we can see this kind of  error:

2007 17:59:11 oracle.jdbc.driver.OracleDriver registerMBeans
GRAVE: Error while registering Oracle JDBC Diagnosability MBean.
javax.management.InstanceAlreadyExistsException: com.oracle.jdbc:type=diagnosability,name=main11.0

'GRAVE' word can be interpreted too as 'SEVERE'.

Changes

After installing SQL DEVELOPER, an Oracle 11g product has been installed on the same machine.
