According to the Java Language Specification (JLS), §12.4, "Initialization of Classes and Interfaces" [JLS 2005]:
Initialization of a class consists of executing its
staticinitializers and the initializers forstaticfields (class variables) declared in the class.
...
The JLS also states in §8.3.2.1, "Initializers for Class Variables" [JLS 2005]
At run time,
staticvariables that arefinaland that are initialized with compile-time constant values are initialized first.
...
Step 3 of the detailed initialized procedure described in JLS §12.4.2 [JLS 2014] permits implementations to ignore the possibility of such recursive initialization cycles.
