Etienne Gagnon has released version 1.1.6 of SableVM, a Java bytecode interpreter (that is, a virtual machine) written in portable C. "SableVM requires an ANSI/ISO C compiler (but preferably GCC) and a POSIX platform. It requires a strong memory model (sequential consistency) on multiprocessor systems." SableVM is available for GNU/Linux. Solaris, Mac OS X, and FreeBSD. Version 1.1.6 AWT and Swing support and fixes a number of bugs. SableVM is published under the GNU Lesser General Public License (LGPL).
IBM's alphaWorks has updated the JAR Class Finder, an Eclipse plug-in for finding JAR files containing a given class for the Java build path of a project, thus helping fix NoClassDefFound errors. "Version 2.0.1 supports Eclipse 2.1 and 3.0. New features include searching in .zip archives. Properties files, as well as .class files, can now be searched for, and the package name can be appended to the search."
