OpenJUMP fails on system with more than 4gb ram

Description

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
