Problem
I saw this list of major version numbers for Java in another post:
Java

23
67
22
66
21
65
20
64
19
63
18
62
17
61
16
60
15
59
14
58
13
57
12
56

49
1.4
48
1.3

Where does this list come from? Is there a specific reference for this? Preferably something that shows minor versions too?

Solution
These come from the class version. If you try to load something compiled for java 6 in a java 5 runtime you'll get the error, incompatible class version, got 50, expected 49. Or something like that.
