That looks like a bug in ReadTTFontFileFunc to me. It's not checking return values at all. From scalerMethod.c in the jdk workspace:

            jbyteArray byteArray = (jbyteArray)
                (*env)->CallObjectMethod(env, scalerInfo->font2D,
                                         sunFontIDs.ttReadBytesMID,
                                         offset, numBytes);
            (*env)->GetByteArrayRegion(env, byteArray,
                                       0, numBytes, (jbyte*)destBuffer);

I don't know why byteArray would be null but it appears to be in this case.
