Assertions in static blocks ?

[Ulf Zibis]

Hi,

in the following example, I have an assert statement in a static block 
of my class.

If accessing the static final constants from another class, the static 
block is not executed.
This causes the assertions to remain un-proofed, even if -ea -esa is set.

Is that correct ?

IMO, assertions should always run, if -ea -esa is set.
