invoking a method through JDWP (cmd: JDWP_ClassType_InvokeMethod) with an array
of a primitive type (such as byte[]) as a method argument results in a back-end
crash.

this is caused by a bug in the function nextArgumentTypeTag (invoker.c):

////////////// begin original code
static jbyte
nextArgumentTypeTag(void **cursor)
{
    char *tagPtr = *cursor;
    jbyte argumentTag = (jbyte)*tagPtr;

    if (*tagPtr != SIGNATURE_END_ARGS) {
        /* Skip any class name or additional array modifiers */
        if ((*tagPtr == JDWP_Tag_ARRAY) ||
            (*tagPtr == JDWP_Tag_OBJECT)) {
            tagPtr = strchr(tagPtr, SIGNATURE_END_CLASS);
            JDI_ASSERT(tagPtr);
        }
        tagPtr++;
    }

    *cursor = tagPtr;
    return argumentTag;
}
////////////// end original code

////////////// begin fixed code
static jbyte
nextArgumentTypeTag(void **cursor)
{
    char *tagPtr = *cursor;
    jbyte argumentTag = (jbyte)*tagPtr;

    while (*tagPtr != SIGNATURE_END_ARGS) {
        /* Skip any class name or additional array modifiers */
        if (*tagPtr == JDWP_Tag_ARRAY) {
            tagPtr++;
            continue;
        }
        if (*tagPtr == JDWP_Tag_OBJECT) {
            tagPtr = strchr(tagPtr, SIGNATURE_END_CLASS);
            JDI_ASSERT(tagPtr);
        }
        tagPtr++;
        break;
    }

    *cursor = tagPtr;
    return argumentTag;
}
////////////// end fixed code
