Ehcache disk store unclean shutdown

Question

I\'m using a cache with disk store persistence. On subsequent reruns of the app I\'m getting the following error:

net.sf.ehcache.store.DiskStore deleteIndexI

Try setting the system property: net.sf.ehcache.enableShutdownHook=true

So, either you can add the following line in the beginning of your program: System.setProperty("net.sf.ehcache.enableShutdownHook","true");

Or, from the command line to pass the property: java -Dnet.sf.ehcache.enableShutdownHook=true ...

Note, the ehcache website does mention some caution when using this shutdown hook: Shutting Down Ehcache

When a shutdown hook will run, and when it will not

The shutdown hook runs when:

• a program exists normally. e.g. System.exit() is called, or the last non-daemon thread exits
• the Virtual Machine is terminated. e.g. CTRL-C. This corresponds to kill -SIGTERM pid or kill -15 pid on Unix systems.

The shutdown hook will not run when:

• the Virtual Machine aborts
• A SIGKILL signal is sent to the Virtual Machine process on Unix systems. e.g. kill -SIGKILL pid or kill -9 pid
• A TerminateProcess call is sent to the process on Windows systems.

Hope it works :)
