jmap

[Brian Gardner]

I'm trying to use jmap to dump a histo of a running vm, version 
jdk-1.6.0.3p4_6.  jmap keeps returning the following error, 'no 
providers installed'.  Are these tools supposed to function?  If not are 
there any alternates?

$ /usr/local/jdk1.6.0/bin/jps
72095 Jps
88259 Bootstrap

$ /usr/local/jdk1.6.0/bin/jmap -histo 88259
88259: no providers installed

$ ps -jax | grep 88259
ee         88259     1 88249 87874    0 I     p0   15:39.48 [java]
