Sthala Narasimhan commented on AMQCPP-712:
------------------------------------------
I use the following connection string to connect to broker
BrokerURL=failover:(tcp://host1:61625,tcp://host2:61625). The AMQConnection
factory to try to create instance and crashes. Did some analysis and see that
the crash happens at the following function call randomUUID@UUID@util@decaf
UUID UUID::randomUUID() {
unsigned char data[16];
SecureRandom secRand;
secRand.nextBytes(data, 16);
long long msb = 0;
long long lsb = 0;
msb = (data[0] & 0xFFLL) << 56;
msb |= (data[1] & 0xFFLL) << 48;
msb |= (data[2] & 0xFFLL) << 40;
msb |= (data[3] & 0xFFLL) << 32;
msb |= (data[4] & 0xFFLL) << 24;
msb |= (data[5] & 0xFFLL) << 16;
msb |= (data[6] & 0x0FLL) << 8;
msb |= (0x4LL << 12); // set the version to 4
msb |= (data[7] & 0xFFLL);
lsb = (data[8] & 0x3FLL) << 56;
lsb |= (0x2LL << 62); // set the variant to bits 01
lsb |= (data[9] & 0xFFLL) << 48;
lsb |= (data[10] & 0xFFLL) << 40;
lsb |= (data[11] & 0xFFLL) << 32;
lsb |= (data[12] & 0xFFLL) << 24;
lsb |= (data[13] & 0xFFLL) << 16;
lsb |= (data[14] & 0xFFLL) << 8;
lsb |= (data[15] & 0xFFLL);
return UUID(msb, lsb);
