The java.xml module consists of multiple components, each with its own configuration and property manager. These components originated from different sources, including third party libraries and legacy products. Over time, as the codebase has stabilized, a portion of the configuration, esp. the ones added by the JDK, may be unified into a module wide configuration. This enhancement will reduce duplication, resolve synchronization issues such as the one reported in JDK-8350189, and break barriers between components so that they share internal implementations, thus fixing issues such as JDK-8331025.
