I'm attempting to run a very simple Java program on unix box using
command:
java -jar HelloWorld.jar
and experience the following error
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
If I run the "top" and "free" unix commands I can't see why there
might be a problem freeing up memory to allocate to the JVM, unless
I'm missing something obvious. Any ideas please help. Thanks.
See below for "top" and "free" output:
