[JavaProperties.plist] escaping not working

[BoykoAlex]

Java Properties object serialization produces for String' value :` looks like this:

my.path=\:

Doesn't look like the language tokenizer/parser likes this. I get the following errors:

extraneous input ':' expecting LineBreak

For a windows path Java string: c:\\path\\file.txt
Serialization:

my.path=c\:\\path\\file.txt

Errors:

missing LineBreak at ':'
missing LineBreak at '\'
missing LineBreak at 'p'
missing LineBreak at '\'
missing LineBreak at 'f'
