HTML Entities bug when used in modular mode (resource not found because in different module)

[hathiphant]

HTML entities are loaded via class com.vladsch.flexmark.util.sequence.Html5Entities which is in flexmark-util-sequence-0.62.2.jar but use resource file /com/vladsch/flexmark/util/html/entities.properties which is in flexmark-util-html-0.62.2.jar. When using Flexmark with Java 9 Jigsaw (--module-path and not --class-path), the file containing definitions of entities can not be loaded (not found).
