SystemOutandErrHandler

public class SystemOutandErrHandler extends Object
Class SystemOutandErrHandler extends PrintStream & is for use within the Application Server. The init is called from PEMain and this creates 2 instances of this class - one for Err & other for Out. This is not expected to be performance intensive and hence more defensive programming is done to reduce risk.
