Eclipse MAT plugin 22.214.171.124606221912. Eclipse Mars.2 Release (4.5.2).|
(Apologies if this is an already known problem, but my searches didn't find anything seemingly related. I'm also a MAT/OQL newbie.)
I installed the plugin via the usual help->install new sw, using http://download.eclipse.org/mat/snapshots/update-site/.
After that any object dereferencing in an OQL select seems to only yield blanks, even if the field in question is clearly non-blank when viewing its attributes (e.g., via clicking on a row and viewing attributes in the inspector tab.)
- SELECT s.name.toString(), s, s.@retainedHeapSize FROM org.eclipse.persistence.sessions.server.ServerSession s
This would have visible values for retainedHeapSize and the instances of ServerSession, but not for s.name.toString(). (Or, for that matter s.name, toString(s.name), or other grasped at straws.)
I uninstalled and back-rev'd to 1.5 via http://download.eclipse.org/mat/1.5/update-site/, ( Memory Analyzer 126.96.36.199505271423 org.eclipse.mat.feature.feature.group Eclipse Memory Analyzer) and de-referencing works again.
See attached screenshot (with probably unnecessary redactions, but oh well.)
Thanks in advance for any help/guidance.
