The section "14.16 The throw Statement" of The Java Language
Specification contains the following:

"If a throw statement is contained in a static initializer (8.5), then
a compile-time check ensures that either its value is always an
unchecked exception or its value is always caught by some try statement
that contains it. If, despite this check, the value is not caught by
some try statement that contains the throw statement, then the value
is rethrown if it is an instance of class Error or one of its
subclasses; otherwise, it is wrapped in an ExceptionInInitializerError
object, which is then thrown (12.4.2). "

The following examples show that exceptions thrown from a static
initializer are not caught. Class "stmt10701a" throws the instance of
"Error" class and class "stmt10702a" throws the instance of
"RuntimeException".
