Hi ... I'm trying to assess a potential memory leak in my system that heavily
uses Nashorn. When I start up a relatively simple environment (simple in terms
of usage compared to our prod env), I quickly see a lot of nashorn stuff. For
example:
object count total size class name
47179 4529184
jdk.nashorn.internal.runtime.RecompilableScriptFunctionData
1413 45216 jdk.nashorn.internal.runtime.Source
1413 33912 jdk.nashorn.internal.runtime.Source$RawData
708 16992 jdk.nashorn.api.scripting.ScriptObjectMirror
The problem is that I don't know how to assess whether this is unusual because
I can't find any online guidance about what these things are and what they
correspond to in terms of Nashorn's public classes/objs like a) nashorn
engines; b) objects in global namespace of individual nashorn engines; c)
ScriptObjectMirrors resulting from engine.eval(..); d) etc. Is there
documentation anywhere of what these things are? Or of how to assess what would
be considered a memory leak? (i.e., an ureasonable proliferation of internal
Nashorn objects)?
thank you for any suggestions
thom.
