    Default How to increase java heap space for CITRUS Report Designer?

    Hi,
    It happened a couple of times that CITRUS Report Designer M7 ran out of memory. How can I increase the java heap space?
    Thanks,
    Diddy

    You can specify it in the *.bat/*.sh files. (The *.exe file is configured for 768MB max heap, which should be sufficient for almost all cases.)

    However, that would only be a temporary band-aid, as there is a memory-leak in the PRD. (We fixed it this weekend, so any build older than that is eating memory for breakfast. The leak happens whenever you hit preview or update parameters.)

    Hi,
    I've been already looking before for the .bat file, but in M7 I can only find the .exe file, which is encrypted. Is there another way to change it?
    Where can I find the latest build?
    Thanks,
    Diddy

    java -XX:MaxPermSize=512m -Xmx512m -jar launcher.jar
