After fix of CR 6215975 "FindClass documentation clarification" in Mustang
the updated JNI specification states the following for FindClass function:
  ---Excerpt-from-spec---
  jclass FindClass(JNIEnv *env, const char *name);

  This function loads a locally-defined class. It searches the directories
  and zip files specified by the CLASSPATH environment variable for the class
  with the specified name.
  The name argument is a class descriptor ( §12.3.2). For example, the descriptor
  for the java.lang.String class is:
                   "java/lang/String"
  The descriptor of the array class java.lang.Object[] is:
                   "[Ljava/lang/Object;"
  ---End-of-excerpt---

However, Sun's JDK (at least 5.0/6.0) permits "Lcom/test/test/Test;"
as name parameter for FindClass, though the name is incorrect here according
to both updated/1.5 JNI specs (for FindClass):
  http://download.java.net/jdk6/doc/guide/jni/spec/functions.html
and JVMS (Chapter 4.2, "The Internal Form of Fully Qualified Class and Interface Names"):
  http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#14757

If compatibility permits, the implementation should be tightened to disallow this.
