Missing +/- setting for VM option 'UseSplitVerifier'

I am running the emma code coverage tool in my system by using the below command,

D:\DeadLockDetection\DDinDOS>java -XX:UseSplitVerifier -cp emma.jar emmarun -jar process-3-1.0.jar

The below error is comming on running the above command,

Missing +/- setting for VM option 'UseSplitVerifier'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

How can i solve this problem.

Answer Source

Error is clear. You must use java -XX:+UseSplitVerifier or java -XX:-UseSplitVerifier

Edit: UseSplitVerifier is boolean option for Oracle's JVM. The - or + after the :. Minus disabled the option, Plus enables the option.

From the above link...

Boolean options are turned on with -XX:+ and turned off with -XX:-. Numeric options are set with -XX:=. Numbers can include 'm' or 'M' for megabytes, 'k' or 'K' for kilobytes, and 'g' or 'G' for gigabytes (for example, 32k is the same as 32768). String options are set with -XX:=, are usually used to specify a file, a path, or a list of commands
