Overview

This PR resolves an IllegalArgumentException that occurs when parsing the Redis INFO command response in a Windows environment. This issue is described in GitHub issue #3099 and is also related to the previously closed issue #1281.

The Problem

On Windows, the Redis INFO command output can contain values with backslashes (\), such as the path to the executable (executable:C:\Users\...). The Converters.toProperties(String) method in spring-data-redis uses java.util.Properties.load() internally to parse this response.

However, Properties.load() treats the backslash as a special escape character. Consequently, it misinterprets sequences like \u in a file path as a Unicode escape sequence, leading to an IllegalArgumentException. This poses a challenge for developers working in a Windows environment.

The Solution

To address this while preserving the existing code structure, I've introduced a minimal change to the Converters.toProperties(String) method. Before calling Properties.load(), all backslashes (\) in the input string are replaced with double backslashes (\\).

Before:

try (StringReader stringReader = new StringReader(source)) {
 info.load(stringReader);
}

After:

String sourceToLoad = source.replace("\\", "\\\\");
try (StringReader stringReader = new StringReader(sourceToLoad)) {
 info.load(stringReader);
}

This simple change ensures that Properties.load() correctly interprets backslashes as literal characters, preventing any parsing errors. The fix is applied to the Converters class, which is shared by both Jedis and Lettuce client implementations, resolving the issue for both drivers.
