So, if DynamicTemplateParser has a cache by Resource, how is it identifying the
resource? Or, just how to avoid the problem?
By the way, now my code looks as following, but not sure it changes the cache
behavior:
public class TrackerDynamic extends Tracker {
private DynamicTemplate dynamicTemplate;
public DynamicTemplate getDynamicTemplate() {
if (dynamicTemplate == null) {
dynamicTemplate = dynamicTemplateParser.parseTemplate(
new StringResource(getTemplateString()));
}
return dynamicTemplate;
}
...
}

Not sure how to fix your issue but I spot another issue.
DynamicTemplateParser has a cache by Resource. It looks like you add to the
cache for every render. It's only a question of time before you hit out of
memory errors.
