A bug in JDK 1.8 Server VM using in memory compile

[Prakash Oraon]

I am compiling a java source (stored in String variable) and using JavaCompiler / CompilationTask to compile the source in memory using JDK 1.8, source compatibility set to 1.7I have the following classes - DynamicCompiler - The main driver program. A, B, C - These classes are refereed from the source. B implements C. Class A, B and C are compiled in three differnt JARS - A.jar, B.jar and C.jar located in C:/Temp/testJpublic class DynamicCompiler {
public static void main(String[] args) {
    String sourceCode = 
            "public class TestMain {\n"+
            "   public static void main(String[] args) throws NullPointerException {\n"+
            "\n"+
            "       A a = new A();\n"+
            "\n"+       
            "       System.out.println(\"Inside Test Main...\");\n"+
            "       a.getB().printB();\n"+
            "   }\n"+
            "\n"+
            "}";

    JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();

    Iterable<String> options = Arrays.asList(new String[] { "-classpath", "C:/Temp/testJ/A.jar;C:/Temp/testJ/B.jar;","-source","1.7"});
    JavaFileManager fileManager = 
            new ClassFileManager(compiler.getStandardFileManager(null, null, null));
    DiagnosticCollector<JavaFileObject> diagnosticListener = new DiagnosticCollector<JavaFileObject>();
    List<JavaFileObject> jfiles = new ArrayList<JavaFileObject>();
    jfiles.add(new CharSequenceJavaFileObject("TestMain", sourceCode));

    CompilationTask complieTask = compiler.getTask(null, fileManager, diagnosticListener, options, null, jfiles);

    if(!complieTask.call()) {
        StringBuffer bufferError = new StringBuffer();
        List<Diagnostic<? extends JavaFileObject>> compliationErros = diagnosticListener.getDiagnostics();
        for (Diagnostic<? extends JavaFileObject> diagnostic : compliationErros) {
            bufferError.append(diagnostic);
        }

        System.out.printf("Errors:%s",bufferError.toString());
    } else {
        System.out.println("Compilation Successfull...");
    }
}public class A {
private B b;

A() {
    b = new B("A");
}

public void printA() {
    System.out.println("Inside A...");
    b.printB();
}

public B getB() {
    return b;
}public class B implements C {
private String name;

B(String name) {
    this.name = name;
}

public void printB() {
    System.out.println("Inside B...");
    System.out.println(name);
}

@Override
public void printC() {
    System.out.println("Inside B.printC");

}public interface C {
    void printC();
}The source (stored in variable sourceCode in class DynamicCompiler) is getting compiled using - java version "1.8.0_11" Java(TM) SE Runtime Environment (build 1.8.0_11-b12) Java HotSpot(TM) Client VM (build 25.11-b03, mixed mode)
But the same source (stored in variable sourceCode in class DynamicCompiler) is not getting compiled using - java version "1.8.0_66" Java(TM) SE Runtime Environment (build 1.8.0_66-b18) Java HotSpot(TM) 64-Bit Server VM (build 25.66-b18, mixed mode)I am getting the following error -Errors:/TestMain.java:7: error: cannot access C a.getB().printB(); ^ class file for C not foundIf I add C:/Temp/testJ/C.jar in the classpath as below, the source is compiled.Iterable options = Arrays.asList(new String[] { "-classpath", "C:/Temp/testJ/A.jar;C:/Temp/testJ/B.jar;C:/Temp/testJ/A.jar","-source","1.6"});Question -Why does the same code gets compiled in JDK 1.8 64-Bit Server VM but not in JDK 1.8 Client VM.? Is there a difference in compilation model between Client and Server VM in JDK 1.8?Thanks, Prakash
