🔒 Fix information exposure vulnerability by using secure logging

[RoiSoleil]

🎯 What

Addressed a security vulnerability in MissingClassTreeContentProvider.java where JavaModelException instances were being output directly to standard error using e.printStackTrace().

⚠️ Risk

Writing stack traces to the standard error stream constitutes an Information Exposure vulnerability (CWE-209). In a production environment, this can expose sensitive information about the application's internal structure, state, and underlying system details to potential attackers. Furthermore, it bypasses centralized logging frameworks, reducing observability.

🛡️ Solution

Replaced e.printStackTrace() calls with the project's standard logging mechanism: LogHandler.getInstance().handleExceptionLog(e). This ensures errors are logged securely and centrally without leaking sensitive details to standard streams. Added the necessary import for org.moreunit.log.LogHandler.

Verified the fix by running the build (mvn clean verify -DskipTests) and confirming there are no Checkstyle or compilation errors. Integration tests were attempted but failed due to headless environment constraints (xvfb-run failures), however the code change is straightforward and safe.
