Japhar is the Hungry Programmers' Java VM. It has been built from the ground up without consulting Sun's sources. It is currently at JDK 1.1.5-level. Japhar is released under the LGPL, which should make it much more attractive for companies interested in embedding an open source JVM in their proprietary/commercial products. For example, the LGPL is compatible with Netscape's NPL license, and allows Japhar to be included into Mozilla.
