Description

When I started the groovy console in the command line, a NumberFormatException was thrown. This is due to try to parse system property named "os.version" as a float value, but failed. Because the value on my machine is "5.1 build 2600 Service Pack 2".
The groovy file the exception thrown is called WindowsDefaults.groovy under package "groovy.ui.view".

Below is the exception stack trace:
