OutOfMemory with the use of WorkingMemoryFileLogger

Hello,

In my tests of the 4.0.3, I have some : java.lang.OutOfMemoryError.

So, I try a simple test with 10.000 sequential execution of 1 rule with no context and just a workingmemorylogger and I have the error : java.lang.OutOfMemoryError: Java heap space

My code is :

public class ExecReglesMemotyTest
{

private static final Reader DRL = new InputStreamReader(ExecReglesMemotyTest.class
.getResourceAsStream("/rules/exemple.drl"));

private static final String FICHIER_LOG = "session";

/**

• @param args
  */
  public static void main(String[] args)
  {
  try
  {
  PackageBuilder builder = new PackageBuilder();
  builder.addPackageFromDrl(DRL);
  RuleBase ruleBase = RuleBaseFactory.newRuleBase();
  ruleBase.addPackage(builder.getPackage());
  for (int i = 0; i < 10000; i++) { StatefulSession session = ruleBase.newStatefulSession(); WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger(session); logger.setFileName(FICHIER_LOG); session.fireAllRules(); logger.writeToDisk(); session.dispose(); }

}
catch (Exception e)

}
}

with this rule (doesn't matter):
#created on: Fri Nov 09 15:48:45 CET 2007
package initPackage

#list any import classes here.

rule "ERG9"
when

then

end

I try this in 4.0.1, and it's working (no OutOfMemoryError)

What's the problem ?

thanks for any information,

V.
