Important Fix println bug, where the OutputTester is causing a violation via FileRead

[sarpsahinalp]

Problem:
We have to be able identify in the callstack which allowed classes are actually calling the methods that are security related
BootstrapMethodError: java.lang.SecurityException: Ares Security Error (Reason: Student-Code; Stage: Execution):de.tum.cit.ase.FileSystemAccessDemo.accessFileSystemViaFilesExecute(FileSystemAccessDemo.java:36) tried to illegally read from /home/sarps/.m2/repository/de/tum/cit/ase/ares/2.0.0-SNAPSHOT/ares-2.0.0-SNAPSHOT.jar via java.io.RandomAccessFile.readFully([B,int,int)but was blocked by Ares.

• Fix runtime exception instead of SecurityException

• Fix tests that include false positives due to RuntimeExceptions that are catched
