Apache Commons - Alternative to Java collection
Commons-Collections seek to build upon the JDK classes by providing new interfaces, implementations and utilities.
- Bag interface for collections that have a number of copies of each object
- Buffer interface for collections that have a well defined removal order, like FIFOs
- BidiMap interface for maps that can be looked up from value to key as well and key to value
- MapIterator interface to provide simple and quick iteration over maps
- Type checking decorators to ensure that only instances of a certain type can be added
- Transforming decorators that alter each object as it is added to the collection
- Composite collections that make multiple collections look like one
- Ordered maps and sets that retain the order elements are added in, including an LRU based map
- Identity map that compares objects based on their identity (==) instead of the equals method
- Reference map that allows keys and/or values to be garbage collected under close control
- Many comparator implementations
- Many iterator implementations
- Adapter classes from array and enumerations to collections
- Utilities to test or create typical set-theory properties of collections such as union, intersection, and closure

Guava - Google Core Libraries for Java
The Google Guava Libraries are a nice set of Java utility classes that will probably come in handy in any project. It provides immutable collections, string manipulation, handling primitives ,easier I/O, concurrency etc. it absolutely follows the Collections API requirements. It has support for murmur hash.
Fastutil - Fast & compact type-specific collections for Java
Fastutil extends the Java Collections Framework by providing type-specific maps, sets, lists and queues with a small memory footprint and fast access and insertion. It also provides also big (64-bit) arrays, sets and lists, and fast, practical I/O classes for binary and text files.
Trove - High performance collections for Java
Trove provides fast, lightweight implementations of the java.util Collections API. These implementations are designed to be pluggable replacements for their JDK equivalents. This gap in the JDK is often addressed by using the "wrapper" classes (java.lang.Integer, java.lang.Float, etc.) with Object-based collections. For most applications, however, collections which store primitives directly will require less space and yield significant performance gains.
Libvirt - The virtualization API
Libvirt is collection of software that provides a convenient way to manage virtual machines and other virtualization functionality, such as storage and network interface management. These software pieces include an API library, a daemon (libvirtd), and a command line utility (virsh). It provides a single way to manage multiple different virtualization providers/hypervisors like Xen, OpenVZ, VirualBox, Microsoft Hyper-V hypervisor, VMware.
