> Issue Type: Bug
> Components: Classlib
> Reporter: Vladimir Ivanov

> According to J2SE specifications for method java.lang.ClassLoader.defineClass(byte[] b, int off, int len):
> "Throws: ClassFormatError - if the data did not contain a valid class "
> But Harmony API +DRLVM throws LinkageError in this case.
> =================== test.java =======================
> public class test {
> public static void main (String [] args) {
> try {
> byte[] array0 = new byte[] { 2, 2, 2, 2, 2, 2};
> new CL().defineKlass(array0, 0, 3);
> System.out.println("exception expected");
> } catch (ClassFormatError e) {
> System.out.println("Test passed: " + e);
> } catch (Throwable e) {
> System.out.println("Test failed: unexpected exception: " + e);
> e.printStackTrace();
> }
> }
> }
> class CL extends ClassLoader {
> public Class defineKlass(byte[] a, int i1, int i2) throws ClassFormatError {
> return super.defineClass(a, i1, i2);
> }
