Good profiler (JProbe vs. JProfiler vs free ones)

hi,

just another tool question: we are having problems with a java process which is taking high cpu load after running for a while. heap-memory consumption is not the problem (could already see this by using jconsole).
to analyze the bottleneck we want to use a profiler.

our tool requirements:
-plugin from outside to a running application/process (like jconsole)
-getting information about cpu-load and which methods/threads are the problem. good analyzation for that

i had a look at JProbe and JProfiler which are promising, but are there other free tools?

thanks for your information

There is a good profiling tool that comes with NetBeans IDE.
