Invalid maximum heap size
Solution 1
You are using 32 bit VM (Java HotSpot(TM) Client VM) which can be mapped to maximum 4G (Only 2 GB in reality) 2^32 address locations Maximum Java heap size of a 32-bit JVM on a 64-bit OS
Error message suggest you are using 5GB heap memory which is not supported on 32 bit architecture
Invalid maximum heap size: -Xmx5096m The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.
You can modify the -Xmx parameter to use anythinng <=2g should work here
Solution 2
I just encountered the problem and solved it by downloading the windows 64-bit JAVA.
Please check whether your windows version is 32-bit or 64-bit, and download the right version of JAVA.

I have copied a jdk directory from another location. Since then, I get the following error message.

Does this mean I will have to re-install the jdk, and not just copy any installation directory? I'm asking this and not trying it out myself because this exercise will have to be done in a client machine.
The current machine is a Windows 2008 server and has 12GB of RAM.

Nisarg Patil almost 4 yearsI am using 64bit version of java and still getting this error, any reason you know?

eel ghEEz almost 2 years@NisargPatil, it's possible to execute Java with an argument containing
-X
options separated by spaces. Then Java will fail to parse this argument.
