Using PyCharm Professional 2019.2.3 from the snap in the Ubuntu store I get the following as of recently. Hatchery is version 0.3.3. Ubuntu is 16.04 (since I need to use Kinetic still).
Apparently you are using too new of a JDK version: java.lang.UnsupportedClassVersionError: edu/umontreal/hatchery/psi/RosInterfaceTypes has been compiled by a more recent version of the Java Runtime (class file version 57.0), this version of the Java Runtime only recognizes class file versions up to 55.0.
