Pentaho BI start error about Quartz Listener

HI,

We faced one error while opening pentaho BI 4.8, the error is about quartz system listener.

PentahoSystem.ERROR_0014 - Error while trying to execute startup sequence for org.pentaho.platform.scheduler.QuartzSystemListener

we just comment following line in the file :- /biserver-ce/pentaho-solutions/systemsystemListeners.xml

<bean id="quartzSystemListener" class="org.pentaho.platform.scheduler.QuartzSystemListener" />

Now it is working fine.

Is there any issues we can face by comment this line ?
