... | <p>
Uses reflection to build a valid hash code from the fields of {@code object}.
</p>
<p>
It uses <code>AccessibleObject.setAccessible</code> to gain access to private fields. This means that it will
throw a security exception if run under a security manager, if the permissions are not set up correctly. It is
also not as efficient as testing explicitly.
</p>
<p>
If the TestTransients parameter is set to <code>true</code>, transient members will be tested, otherwise they
are ignored, as they are likely derived fields, and not part of the value of the <code>Object</code>.
</p>
<p>
Static fields will not be included. Superclass fields will be included up to and including the specified
superclass. A null superclass is treated as java.lang.Object.
</p>
<p>
Two randomly chosen, non-zero, odd numbers must be passed in. Ideally these should be different for each class,
however this is not vital. Prime numbers are preferred, especially for the multiplier.
</p>
@param <T>
the type of the object involved
@param initialNonZeroOddNumber
a non-zero, odd number used as the initial value. This will be the returned
value if no fields are found to include in the hash code
@param multiplierNonZeroOddNumber
a non-zero, odd number used as the multiplier
@param object
the Object to create a <code>hashCode</code> for
@param testTransients
whether to include transient fields
@param reflectUpToClass
the superclass to reflect up to (inclusive), may be <code>null</code>
@param excludeFields
array of field names to exclude from use in calculation of hash code
@return int hash code
@throws IllegalArgumentException
if the Object is <code>null</code>
@throws IllegalArgumentException

Each operating system has its own method of handling date changes such as
leap seconds(e.g. OS will slow down the clock to accommodate for this).
(2). DST(Daylight Saving Time) is a legal issue, governments changed it
over time. Some days are NOT exactly 24 hours long, it could be 23/25 hours
long on the first or last day of daylight saving time.
JDK can handle DST correctly.

The specified offset should be the offset of the next record that will be read from partitions.
This lets the consumer ignore any committed group offsets in Zookeeper / Kafka brokers.
<p>If the provided map of offsets contains entries whose {@link KafkaTopicPartition} is not subscribed by the
consumer, the entry will be ignored. If the consumer subscribes to a partition that does not exist in the provided
map of offsets, the consumer will fallback to the default group offset behaviour (see
{@link FlinkKafkaConsumerBase#setStartFromGroupOffsets()}) for that particular partition.
<p>If the specified offset for a partition is invalid, or the behaviour for that partition is defaulted to group
offsets but still no group offset could be found for it, then the "auto.offset.reset" behaviour set in the
configuration properties will be used for the partition
<p>This method does not affect where partitions are read from when the consumer is restored
from a checkpoint or savepoint. When the consumer is restored from a checkpoint or
savepoint, only the offsets in the restored state will be used.
