Free alternatives to Java YourKit profiler
<p>I really like YourKit Java profiler because it is easy to use and integrates nice with Eclipse.</p>

<p>The sad part is I can not afford a license. Are there any java developers out there that are using open source profilers with Eclipse integration? I know there is a PTP project within eclipse but the tooling is pretty lousy and they have stopped active development. </p>

<p>If anyone could offer some free altneratives it would be much appreciated.</p>
