Steps to reproduce:
1. Use keytool.exe to create a keystore with a password, and a key with the a password
2. Load Unity and set it to use the built-in open-jdk implementation
3. In Unity's Android Player settings, select this keystore, or enter the Keystore Manager and select the keystore
4. Enter the password for the keystore (or in the Keystore Manager, enter the password and select Load Keys)
5. Receive an error - Unable to list keys in the keystore. Please make sure the location and password of the keystore is correct.
6. Note in the error message that the -storepass argument passed to keytool.exe is the password you provided (e.g. foo_bar) but quoted using single-quotes (e.g. -storepass 'foo_bar')
6 Run cmd.exe and copy the command line from the error message and run it, receive an error
7. Remove the single-quotes from the -storepass argument, run it again, see that it works

Expected result: storepass parameter should not be quoted
