Examples with JCJavaClassLoader com.ibm.dtfj.java.javacore.JCJavaClassLoader used on opensource projects

Example 1 with JCJavaClassLoader

use of com.ibm.dtfj.java.javacore.JCJavaClassLoader in project openj9 by eclipse.

the class JavaRuntimeBuilder method addClassLoader.

/**
 * Must pass a valid class loader ID in order to generate a class loader object. Else exception
 * is thrown.
 *
 * @param classLoaderName optional
 * @param clID required, or else exception is throw and class loader is not created.
 * @param objectID optional (although generally this is the same as the clID for most javacores)
 * @return successfully created JavaClassLoader
 * @throws BuilderFailureException if class loader ID is invalid.
