Bug ID: 21397
Summary: java .return probes should support method's return
value
Product: systemtap
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: translator
Assignee: systemtap at sourceware dot org
Reporter: dsmith at redhat dot com
CC: penguin-kernel@i-love.sakura.ne.jp
Target Milestone: ---
It should be possible to support a systemtap $return style variable in
java().class().method().return probes.
This would use byteman's '$!' special variable, as seen at the following link:
<http://downloads.jboss.org/byteman/3.0.8/ProgrammersGuide.html#rule-expressions>
Byteman version 3 supports '$!', systemtap supports version 2.0+, we'll have to
see if that version also supports '$!'.
This was suggested by the following email:
