The Code Review Patch challenges are designed to enhance your skills in identifying vulnerabilities within the code by presenting both the original, flawed code and the subsequent patch. Your task is to scrutinize the provided code and pinpoint the security flaws before looking at the patch. This approach encourages you to develop a keen eye for common coding errors and security pitfalls.

In this specific challenge, you are given a Java class `SourceType.java` from Apache CXF's Aegis module, which deals with XML transformation. The provided diff file highlights changes made to the code to address a security vulnerability. By comparing the original and patched code, you can learn about the specific modifications implemented to mitigate the identified issue, such as disabling DTDs to prevent XML external entity (XXE) attacks. This exercise not only reinforces your understanding of secure coding practices but also familiarizes you with real-world scenarios where such vulnerabilities may arise.
