You may have come across the different ways that Development uses to indicate more than one version of a Product,
namely " .x" vs " +".
While working through our certification documentation some people came across this and had a little chat with Development about it. Here is the simple yet easy to understand response that they got:
188.8.131.52.x, the "x" indicates to include:
184.108.40.206+, the "+" indicates any higher version of the same codeline e.g.
but not 11.1.2... nor 12...
One minimal yet important difference is, that the "+" usually is NOT separated by a dot, while the x is. So the versions referenced by the "+" are one level up from those referenced by the ".x"
We hope that this settles the question once and for all. So the next time you need to check a product compatibility via the product matrices or the certification tab, you will no longer have to worry about the question if JRE 1.6_34+ includes JRE 1.7_15 or not - you now know that it does not.
