FreeMarker 1.6 is a recommended update for Solaris users in a production environment. Under high stress conditions, previous versions of FreeMarker could cause the Solaris JVM to run out of file handles.
FreeMarker 1.6 includes bug fixes that ensure file handles are always closed once they are no longer needed, rather than relying on the garbage collector to do this.
This bug is not known to cause problems for JVMs other than the Solaris JVM supplied by Sun.
