Running with gdb gives the following output. I can't install debug symbols for java atm. I will do this next week. But at least gdb tells us which address it wants to access. 08:01:07.529 [main] INFO org.quartz.impl.StdSchedulerFactory - Quartz scheduler 'BoxClient Scheduler' initialized from default file in current working dir: 'quartz.properties' 08:01:07.531 [main] INFO org.quartz.impl.StdSchedulerFactory - Quartz scheduler version: 2.2.1 08:01:07.539 [main] INFO org.quartz.core.QuartzScheduler - JobFactory set to: com.in2soft.remote.client.scheduler.SchedulerJobFactory@1b487e4 Cannot access memory at address 0x28 Program received signal SIGSEGV, Segmentation fault.
