Subject [jira] Resolved: (DIGESTER-125) Memory leak in Digester class by inputSources collection
Date Mon, 09 Jun 2008 15:03:45 GMT


Simon Kitching resolved DIGESTER-125.

    Resolution: Fixed

Thanks for pointing this out. The cleanup method has been modified to now clear the inputSources
list (svn commit r665710).

Note, however, that reusing a Digester instance is not recommended. See the wiki FAQ:

I'll add some info about that to the Digester class javadocs.

> There is no clean method for inputSources list from Digeste class, 
> in frequent usage of parse() method inputSources collection will collect references to
sources objects. In this situation the number of object references represented by sources
from inputSources,
> will be increased and consume a lot of memory. For intensive parsing smth around 200
mb for 8 hours was consumed.
> Solution is simple method cleanup() should contain line inputSources.clear(); at the
end of the method.
