Atsushi Isobe updated VELOCITY-715:
-----------------------------------
Description:
org.apache.velocity.runtime.resource.loader.FileResourceLoader#templatePaths
has stored templatename and real file path permanently.So if
VelocityEngine#getTemplate(String) has called by too many files, #templatePaths
have been enlarged.
Bellow my test results.
