RCE releases are provided for Windows and Linux. It is regularly tested on
Windows 7
Windows 10
Windows Server 2016
CentOS 7
Debian 9
SUSE Linux Enterprise Desktop ("SLED") 12 SP2
Ubuntu 18.04 LTS
Starting with release 8.0.0, RCE is only shipped for 64 bit systems. If you still require 32 bit packages, you can continue to use previous RCE releases, but there will be no standard feature or bugfix updates for them.
On Red Hat Enterprise Linux 7 with KDE 4, RCE (like any other Eclipse-based application) can cause a segmentation fault at startup. If you encounter such an issue, you can try choosing a different GTK2 theme:
Open the System Settings application (systemsettings).
Go to Application Appearance
Open GTK page
Switch the GTK2 theme to "Raleigh" or "Adwaita" and click on Apply
On Unix Systems using KDE as desktop environment and Oxygen as theme it can happen that RCE crashes when certain GUI elements are shown. It is a known issue in the theme Oxygen and happens on other Eclipse-based applications as well. If you encounter such an issue, please choose a different theme like "Raleigh" or "Adwaita".
The Script component can use Jython for the evaluation of scripts and the pre- and postprocessing of integrated tools always uses Jython. Due to a known bug in the Jython implementation it is not possible to execute several Jython instances in parallel. Therefore, the execution will be done sequentially. If several Script components should be executed in parallel, Python should be used instead.
Running RCE with a 32-bit Java Runtime Environment doesn't work. On some operating systems an error dialog will be displayed in this case, on some other systems nothing will happen at all. Therefore, always make sure a 64-bit Java Runtime Environment is used to run RCE.
