    protected void initProperties(PropertyManager propMgr) {
        BlockProps blockProps = propMgr.getBlockProps();
        textIndent = blockProps.firstIndent;

blockProps is initialized in the constructor of LineLM.

    public BlockProps getBlockProps() {
        BlockProps props = new BlockProps();
        props.firstIndent = this.propertyList.get(PR_TEXT_INDENT).getLength();
        return props;

If this.propertyList is not null, then get(PR_TEXT_INDENT) always
returns a value; if it is not specified by the user, the default value
is returned. This is true for all properties.

    public Length getLength() {
        return this;

    public Length getLength() {
        return null;

getLength(), however, may return a null value. It only returns a
non-null value if the property returned by get(PR_TEXT_INDENT) is a
LengthProperty. This should be true; I do not know a reason why it is
not true in your code.
