Why JVM not able to start on Windows XP when maximum heap space around 1600M?
This problem is most obvious on Windows platform like Windows XP, which tries to allocate a contiguous chunk of memory as requested by -Xmx JVM parameters. Windows reserves some space for his own and seems also allocate memory around half of memory address bar, which consequently reduces contiguous memory space somewhere less than 2GB, around 1500 to 1600M and when you give more than this size, JVM throws error as. Could not create the Java virtual machine. Invalid initial heap size: -Xms1.5G
