actionHero/node-java signal handling (Ctrl+c or kill -9)

[coderReview]

Hi,

I am using actionHero to deploy a web application and I am trying to use the node-java to access a database with JDBC.

Everything seems fine, but when I kill the actionHero application (either with ctrl+c or kill -9) the actionHero does not perform its teardown methods.

If I don't use the node-java package the actionHero terminates gracefully. It seems that the node-java package is preventing the signal to reach the actionHero plataform.

Thanks,

I have found two possible solutions. It looks like if you initialize node-java and call a java method before adding node shutdown hooks node appears to receive the shutdown message. Another method which I have updated the README (see the very bottom) to include is to call the java shutdown hook methods and then perform shutdown actions there.

Using the -Xrs option could help ? I can't try it out right now.

Thanks

Using the -Xrs option does the trick all right:

java.options.push('-Xrs');

Use before any other node-java code as stated in read me.

Thanks

Just be sure to call System.exit(0) before the application ends to shutdown JVM and call all shutdown hooks.
