question: private static void fixPrng ( ) { if ( ! prngFixed . get ( ) ) { synchronized ( PrngFixes . class ) { if ( ! prngFixed . get ( ) ) { PrngFixes . apply ( ) ; prngFixed . set ( true ) ; } } } }
target:  Ensures that the PRNG is fixed. Should be used before generating any keys. Will only run once, and every subsequent call should return immediately.
