Hi,

In my JVM args when running a project in intellij, all jvm args are recognized (set heap and so fourth), but when i start adding XX args such as
-XX:+UseCompressedOops
-XX:-PrintGCDetails

it gives me errors:
Could not create the Java virtual machine.
Unrecognized VM option '+UseCompressedOops'

Any ideas?

Thanks,
Alex

You need to check which XX arguments are available for the particular vm the IDE is using

probably your JVM is 32 bit or your heap size specified by -Xmx parameter is more than 32GB. each one of this reasons will cause "Could not create the Java virtual machine".

I've set every parameter to no more then 1GB.  I believe the reason its failing is because its not recognizing the VM option via -XX parameter

Unrecognized VM option '+UseCompressedOops'
is the reason it's failing. See my comment above and print the XX options for the vm you're using

are you using SUN java?
what is the output of this?
System.out.println("JVM type: " + System.getProperty("sun.arch.data.model"));
System.out.println("JVM type: " + System.getProperty("os.arch"));

and this: java -version from dos prompt
