Example 19 with MBeanServer

use of javax.management.MBeanServer in project neo4j by neo4j.

the class JmxQueryProcedureTest method shouldConvertAllStandardBeansWithoutError.

    //      .. we don't assert more than this, this is more of a smoke test to ensure
    //      that independent of platform, we never throw exceptions even when converting every
    //      single MBean into Neo4j types, and we always get the correct number of MBeans out.
