Typically IntegerCache::<clinit> runs before JIT has even started, so
I think we're OK even though the double-assignment is undefined. But
it's a good question what happens in cases we're running AOTd code,
so perhaps this pattern might be problematic in some future..
What if you run it with -Xcomp ?
Works.
Would still be run by interpreter at startup?
Yes, -Xcomp doesn't change when JIT threads start running; verified on a
debug build that IntegerCache.<clinit> is executed by the interpreter
even with -Xcomp
