Hi,
thanks for your report.
jvmtop does currently only officially support jvms with a version >= 1.6.0
All earlier jvms - which end-of-life date has been reached since years - are
not supported.
The chances are high that this is one major cause of the problem and cannot be
workarounded (beside upgrading your jvm)
The other important thing to understand is that jvmtop works totally differant
than tools like "ps" or "top" do.
There's a significant difference if you can see a process via ps (which is true
for most - if not all - processes in a regular unix operating system) or a
process which jvmtop can detect and attach.
jvmtop uses the java management APIs to detect and attach to other jvms.
There are several java security barriers (depending on the jvm and its
configuration) which jvmtop cannot override. If this would be the case, the
security mechanisms would become obsolete.
You should try running jvmtop under the "wasadmin" or "root" user or try
lowering rmi security if this is an option for you.
I'm sorry that I do not see other options.
However, I would like to encourage everyone to submit patches to improve the
attach compatibility, especially with very old jvms.
