When the entity contains a transient dateformatter that is used in the toString() a NPE is thown for whatever reason. My Entity looks like this:

public class SomeEntity  {

	.
	.

	@Transient
	private DateFormat dateFormatter = new SimpleDateFormat();
	
	.
	.	

	@Override
	public String toString() {
		StringBuilder builder = new StringBuilder();
		builder.append("datum=");
		builder.append(datum != null ? 
                   dateFormatter.format(datum.getTime()) : datum);
		return builder.toString();
	}
	
}

I use Eclipselink in a OSGI-Environment, but I gues that does not make a difference. Stack Trace just says:

[EL Warning]: weaver: 2013-01-30 12:04:46.551--Weaver encountered an exception while trying to weave class XY.  The exception was: java.lang.NullPointerException

I wish the stack trace would contain a line number of the NPE.
