freemarker wont clear its internal caches - OOM after several thousand runs about xdocreport HOT 2 CLOSED

ok, first looking into the code then "complaining"... I fixed it by using a report ID to load a template:

// getAttribute("template",defValue) returns the template URI/URL so its unique
IXDocReport report =XDocReportRegistry.getRegistry().loadReport(tmplIn,getAttribute("template",null),TemplateEngineKind.Freemarker);

from xdocreport.

To have a very good performance, you must use IXDocReportRegistry#loadReport the first time and IXDocReportRegistry#getReport the second time. See https://code.google.com/p/xdocreport/wiki/DocxReportingJavaMain#5._Test_Performance

By default XDocReport uses Freemarker cache. If you don't wantt o use this cache (and not use loadReport/getReport) you can call for instance this loadReport https://github.com/opensagres/xdocreport/blob/master/document/fr.opensagres.xdocreport.document/src/main/java/fr/opensagres/xdocreport/document/registry/XDocReportRegistry.java#L284
with cacheReport to false.
