Field Detail

debug

public static final boolean debug

A flag used for a variety of purposes during performance tuning. The use of the flag makes it easier to figure out where those System.err messages are coming from. This should always be off in the trunk.

echoProcessStartupLineCount

public static int echoProcessStartupLineCount

The #of lines of output from a child process which will be echoed onto System.out when that child process is executed. This makes it easy to track down why a child process dies during service start. If you want to see more output from the child process, then you should set the log level for the ProcessHelper class to INFO.

threadLocalBuffers

Global switch controlling whether true thread local buffers or striped locks are used for some things.
