Robert Oloffson has posted version 0.47 of Java Memory Profiler (JMP). JMP uses the Java Virtual Machine Profiling Interface (JVMPI) interface to track objects and method times in a JVM. It uses a GTK+ interface to display statistics. The current instance count and the total amount of memory for each class is shown as is the total time spent in each method. 0.47 makes various minor improvements. JMP is written in C for Linux.
