RFR: Added tests to represent bad stream handling in jdec and correct one in jdis

[Jiří Vaněk]

The tests are now maven only. I do not knwo how to add them properly to the ant task, without introducing ivy to download junit jupiter runner, or to add burden of some wgetted dependencies.

WDYT?

The tests represents the issue with messe dusp tream in jdecoder, and correct behaviour in jdis.
I hoped I will provide fix asap once the tests ar ehere, but the inheritance there was quite a surprised, so now I'm double checking what would be actually broken by the "swap" of the jdec streams back to "normal".
Do you have some quick guidance how to force somethng to loggerOutput please?
