Related Issues:

Start with Utils.java at getConfigFilePath(Utils.java:98), reached by running ciphertool.bat -Dconfigure from the product's <carbon_home>/bin directory on Windows. Reproduce the failure and verify that the generated security keystore path no longer contains the duplicated Windows drive prefix and that initialization completes without InvalidPathException.
