Author: jmd Date: Sat Apr 1 17:58:59 2017 New Revision: 437452 URL: https://svnweb.freebsd.org/changeset/ports/437452 Log: new port: java/lightweight-java-profiler A port of the lightweight-java-profiler (ljp). ljp acts as a bare-bones agentlib to produce profiling stacks that can be digested, e.g., by Brendan Gregg's flamegraph scripts.
