Error with backslash in Windows path for inatallation tests

When execute Continuum webapp test in Windows I get error in intallations tools tests.

It is because when the java.home and maven.home variables are replaced in properties file, they are interpreted incorrectly, backslash '\' is interpreted how a character for escape other character.

Example: If java.home = C:\java\jre1_5 you will get C:javajre1_5
