I'm calling the run() method of Antrunner, while executing the body of run() at line 323 - classInternalAntRunner = getInternalAntRunner(); enters into the getInternalAntRunner() . I get the following message when the getInternalAntRunner() is executed at line - "return loader.loadClass("org.eclipse.ant.internal.core.ant.InternalAntRunner"); //$NON-NLS-1$"

java.lang.NullPointerException

The same code when executed on Eclipse 3.6, Build id: 20100318-1801 it works fine. both are executed on windows xp Professional, SP 3. 

Reproducible: Always

Steps to Reproduce:
1. have a build.xml that compiles and jars some java files
2. call org.eclipse.ant.core.AntRunner.run()
3. we get java.lang.NullPointerException

How exactly are you calling the run() method? How are you configuring AntRunner prior to running it?
Comment 3 Mahesh Maney CLA 2011-12-07 03:02:57 EST 
// I create  an object of AntRunner.
     AntRunner ar = new AntRunner();
// Set the absolute path of the build.xml file
ar.setBuildFileLocation(buildFile);
// Set all the required jar files to the class path;
    // jdk1.6.0_11/lib/tools.jar;
    //lib/ant.jar, 
    //lib/ant-apache-oro.jar,
    //lib/ant-jai.jar, 
    //lib/ant-junit.jar, 
    //lib/ant-jsch.jar, 
    //lib/ant-antlr.jar, 
    //lib/ant-launcher.jar, 
    //lib/ant-netrexx.jar, 
    //lib/ant-apache-bsf.jar,
    //lib/ant-jmf.jar, 
    //lib/ant-jdepend.jar, 
    //lib/ant-swing.jar, 
    //lib/ant-commons-net.jar
    // mU is an URL array containing the URL of all the mentioned jar files
ar.setCustomClasspath(mU);
// set up a file to record activity 
setMessageFile(ar,opFolder);
try {
      // Calling the run() method now.
      ar.run(m);
} catch (Exception e) {
      e.printStackTrace();
}

After the call to the run(), it enters AntRunner class's run() at line 313
At line # 323 - classInternalAntRunner = getInternalAntRunner(); is executed throwing a null pointer exception.

is this the information you looking for Mike ? anything more expected please let me know.
