BPEL deployer should not be using PublishCopyUtili.java in JBoss as.core package

Like the comments in PublishCopyUtili say:

• This class/interface is part of an interim API that is still under development and expected to
• change significantly before reaching stability. It is being made available at this early stage to solicit feedback
• from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
• (repeatedly) as the API evolves.

the bpel deployer package probably shouldn't be using this class, but should be using the standard WTP API instead.
I've made a quick fix for now to get us through M2, but this needs to be addressed before final release.
