Good idea re pasting in a browser. So I did that. And it fails, with the same error the OP is seeing.
<br>
<br>
So hmm. Unless I screwed up the test somehow, that implies that there is some sort of legitimate issue here. If someone else with a test IdP handy (and who knows what they are doing) can reproduce, that will eliminate operator error.<br>
<br>
Testing IdP was a 3.4.0-SNAPSHOT, just updated to latest JDK 1.8.0_141.<o:p></o:p></p>
