> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.7
> Environment: Windows, Java 1.6, low heap (-Xmx10m)
> Reporter: Marnix Bindels
> Priority: Minor
> Attachments: VelocityOutOfMemoryTest.java, heap.png, script_1.vm, script_2.vm, script_3.vm

> I was testing a template collection that uses #parse inside some #foreach, which worked all fine inside eclipse but crashed when used in the stand-alone application running with a low heap setting with an OutOfMemoryError: Java heap space. I was able overcome this by setting the <loader>.resource.loader.cache to "true".
> Still I wanted to let you know about this as it may be an indicator of a resource management issue of sorts anyway. The parsed resource is constant, with caching off it gets reported as found and loaded by the ResourceManager for each iteration (some 6000 times in the example). I understand that without caching it gets loaded every time, but why do the previously loaded instances keep occupying memory?
> When published on teh dev mailing list, it was suggested to file this bug report.
