RFR: 8237508: Simplify JarFile.isInitializing

[Daniel Fuchs]

Hi Claes,

Looks OK to me but I'd have a slight preference to a solution
that confines the hack to the JarFile class.

Would making the isIntializing field private and introducing
a static boolean isInitializing() method in JarFile bring the
same benefits WRT startup?

best regards,
