toString() q params, missing &

[bitsofinfo]

URN_8141 urn = URN.rfc8141().parse("urn:XY:ORDER:111111?=x=y&z=c");
System.out.println(urn.toString());
System.out.println(urn.toURI().toString());

urn:LB:ORDER:111111?=x=yz=c
urn:LB:ORDER:111111?=x=yz=c

where are the & separators?

I'm running 2.0.1....

This is a strange bug. Ampersands in the query component are implemented. This is the output on my machine, running Java 8:

urn:XY:ORDER:111111?=x=y&z=c

What Java version are you running on?
