OpenJUMP fails on system with more than 4gb ram

[hamish]

For the OSGeoLive 8.0 disc we use 32bit Lubuntu with the linux pae extensions, allowing the OS (but not processes) to access to more than 4gb ram.

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
