  An extensive management functionality is one of the key advantages of the MicroTCA.4 standard. Monitoring and control of more than 350 MicroTCA crates and thousands of AMC and RTM modules installed at XFEL, FLASH, SINBAD and ANGUS experiments has been integrated into the DOOCS-based control system. A DOOCS middle layer server together with Java-based GUIs - JDDD and JDTool - developed at DESY, enable remote management and provide information about MicroTCA shelves and components. The integrated management includes inventory information, monitoring current consumption, temperatures, voltages and various types of the built-in sensors. The system event logs and collected histories of the sensors are used to investigate failures and issues.

  The Java Doocs Data Display (jddd) is a Java-based tool for creating and running graphical user interfaces for accelerator control systems. It is the standard graphical user interface for operating the European XFEL accelerator. Since Java 8 Oracle introduced a number of major changes in the Java ecosystem’s legal and technical contexts that significantly impact Java developers and users. The most impactful changes for our software were the removal of Java Web Start, Oracles new licensing model and shorter release cycles. To keep jddd up to date, the source code had to be refactored and new distribution concepts for the different operating systems had to be developed. In this paper the benefits and pitfalls of the jddd migration from Oracle Java8 to OpenJDK11+ will be described.
