[Wrapper-user] stop call overriding restart filter

[Patrick W. <wo...@em...>]

I using the wrapper to control an app that uses an ill-behaved library.
 I set a filter to detect the string "Out of Memory" which the library
will spit out before it calls System.exit().  However in testing it
looks like after the filter is triggered the wrapper is being told to
shutdown and this overrides the restart behaviour.  Is there any way to
make the restart take precedence regardless of what comes later?

My filters are configured as:

wrapper.filter.trigger.1=java.lang.OutOfMemoryError
wrapper.filter.action.1=RESTART
wrapper.filter.trigger.2=Out of Memory
wrapper.filter.action.2=RESTART

And here is the output of my log file:
