The TCK's have always been the center of much discussion / cause of friction in the Java community. Although most discussions were about the Java SE TCK, not the EE TCK. All this friction goes back to the Sun days. Apache Harmony was probably the pinnacle of TCK friction. This is the open letter the Apache foundation send to Sun: https://www.apache.org/jcp/sunopenletter.html https://www.apache.org/jcp/sunopenletter.html I realise that Oracle only open sources the TCK because they no longer want to carry the burden of EE (can't say I blame them) but its still ironic that Sun never wanted to release most TCK's and now Oracle releases the EE TCK.
