LevenshteinDistance	Utility for string comparison based on the Levenshtein algo.
LikeUtil	Utility for performing a SQL Like comparsion.
ManagedReadWriteLock	Simple read-write lock based on ReentrantReadWriteLock that associates a name with the lock and traces read/write locking and unlocking.
MethodResolver	Used for retrieving static and instance method objects.
MetricUtil	Utility for CPU and wall time metrics.
MultiKeyCastingComparator	A comparator on multikeys.
MultiKeyCollatingComparator	A comparator on multikeys with string values and using the Collator for comparing.
MultiKeyComparator	A comparator on multikeys.
MurmurHash	This is a very fast, non-cryptographic hash suitable for general hash-based lookup.
NullableObject<T>	A generic class to hold an object that may itself be a null value versus an undefined (not existing) value.
ObjectCollatingComparator	A comparator on objects that takes a boolean array for ascending/descending.
ObjectComparator	A comparator on objects that takes a boolean array for ascending/descending.
ObjectInputStreamWithTCCL
OnDemandSunReflectionFactory
PlaceholderParser	Parser for strings with substitution parameters of the form ${parameter}.
PlaceholderParser.Fragment	Fragment is a parse result, a parse results in an ordered list of fragments.

SimpleTypeCasterAnyType	Cast implementation for non-numeric values that caches allowed casts assuming there is a small set of casts allowed.
SimpleTypeCasterFactory	Factory for casters, which take an object and safely cast to a given type, performing coercion or dropping precision if required.
SimpleTypeParserFactory	A factory for creating an instance of a parser that parses a String and returns a target type.
SQLTypeMapUtil	Utility for mapping SQL types of Types to Java classes.
ThreadLogUtil	Utility class for logging threading-related messages.
