Last month the OSS/J Discovery API (JSR254) passed the final JCP approval. Just like the Order Management and Fault Management APIs, the TCK for the Discovery API is based on the OSS/J TCK Foundation. As explained here the OSS/J TCK Foundation makes the life of OSS/J TCK developers a lot easier and helps them to create better quality TCKs for their APIs.
The nice point about this particular TCK is that the Discovery TCK team was able to develop the Discovery TCK without me supporting them. I accidentally discovered that they released the TCK and that it used the OSS/J TCK Foundation and was pleasantly surprised. I hope it's a sign a maturity that teams are able to use the TCK Foundation without asking me for support once :-)
