On a test of the 8.0 mini on a system with 16gb ram, or a VM with 5gb RAM, OpenJUMP fails to start. If you try from the command line you get the following error message: {{{ $ openjump limit max. memory to 3072 MiB Running -> '/usr/lib/jvm/java-7-openjdk-i386/jre/bin/java'; java version ""1.7.0_65""; OpenJDK Runtime Environment (IcedTea 2.5.1) (7u65-2.5.1-4ubuntu1~0.14.04.1); OpenJDK Server VM (build 24.65-b04, mixed mode); Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. press Enter to finish }}} Looking in the /usr/bin/openjump startup script I see some special 32bit $MEM_MAX logic. If I change the value there for max on 32bit down to 2716000000, or simply comment out the JAVA_MAXMEM line, then it starts up ok. thanks, Hamish",defect,closed,major,OSGeoLive8.0,OSGeoLive,fixed,openjump,edso
