Description

-When configuration context is loaded about 400 times using createConfigurationContextFromFileSystem( ), and hotdeployment is set to true, the following error occurs: java.io.IOException: Too many open files.
-if hotdeployment is set to false, this error does not occur even after loading configurationContext 100,000 times
-if there is a check in getURLsForAllJars() in org.apache.axis2.deployment.util.Utils to see if a URL has file protocol (and not creating a temp file if it does) the threshold is raised to 2826 times, after which an OutOfMemoryError occurs.

The JUnit test is:

import org.apache.axis2.context.ConfigurationContext;
import org.apache.axis2.context.ConfigurationContextFactory;
import junit.framework.TestCase;

public class LoadConfigFromFileTest extends TestCase {

public LoadConfigFromFileTest(String name)

{ super(name); }

public void testLoadConfig1000Times()
{
try
{

ConfigurationContext configContext = null;

String axis2Conf = "C:\\Java\\axis2\\conf
axis2.xml";
String repoDir = "C:\\Java
axis2";

for( int i = 0; i < 1000; i++)

{ System.out.println("Iteration " + i); configContext = ConfigurationContextFactory.createConfigurationContextFromFileSystem( repoDir, axis2Conf); configContext = null; }

}
catch (Exception e)

{ e.printStackTrace(); }

}
}
