I have a legacy web application using quartz 1.5.0, wraped using fulcrum.
After a system crash, when restarting Apache tomcat (hosting the application) I get an error:
Caused by: org.quartz.ObjectAlreadyExistsException: Unable to store Trigger with name: 'xxx' and group: 'yyy', because one already exists with this identification.

Quartz configuration (file quartz.properties):
org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 1
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
org.quartz.jobStore.misfireThreshold = 60000
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
As far as I can understand, quartz schedule is stored in RAM. Right?
Question 1: I have tried to restart tomcat, and even the whole virtual machine. Why does the error persist? I suppose the RAM should be cleared and everything should be restarted.
Question 2: Supposing that I miss something, where could the quartz jobs be stored? I looked in the system's database but I could not find anything relevant.
Question 3: Could I somehow enforce quartz to restart without changing the app code?
Please note that this is a legacy web application which I don't even have the source code of.
