Hi,
Please review and help me with integration:
Problem: java.math.BigInteger.BigIntegerTest uses java.math.Random(), so we have no possibility to reproduce it.
Solution: Test gets start random seed from environment variable. If this variable not exists, test write current random seed to log.
Bug: https://bugs.openjdk.java.net/browse/JDK-8051861 Fix: (in attachment)
Best regards, Vasily
