The Jakarta-ORO Java classes are a set of text-processing Java classes that provide Perl5 compatible regular expressions, AWK-like regular expressions, glob expressions, and utility classes for performing substitutions, splits, filtering filenames, etc. This library is the successor to the OROMatcher, AwkTools, PerlTools, and TextTools libraries from ORO, Inc. (www.oroinc.com). They have been donated to the Jakarta Project by Daniel Savarese (www.savarese.org), the copyright holder of the ORO libraries. Daniel will continue to participate in their development under the Jakarta Project.
Jamm provides MemoryMeter, a java agent to measure actual object memory use including JVM overhead.
Janino is a super-small, super-fast Java compiler. Not only can it compile a set of source files to a set of class files like the JAVAC tool, but also can it compile a Java expression, block, class body or source file in memory, load the bytecode and execute it directly in the same JVM. Janino is not intended to be a development tool, but an embedded compiler for run-time compilation purposes, e.g. expression evaluators or "server pages" engines like JSP.

Jansi is a small java library that allows you to use ANSI escape sequences in your Java console applications. It implements ANSI support on platforms which don't support it like Windows and provides graceful degradation for when output is being sent to output devices which cannot support ANSI sequences.
Small library for parsing and writing JSON documents.
