Exception while running EvoSuite tests related to Security manager

Question

I'm trying to run EvoSuite tests with this tutorial.

I'm able to generate test classes and compile them using java 8. However, when try to run it using the below command, an exception is thrown.

java  -cp ".\log4j.jar;.\ojdbc6.jar;.\commons-codec-1.3.jar;.\slf4j-log4j12-1.7.16.jar;.\slf4j-api-1.7.16.jar;D:\proj\target\classes;.\evosuite-tests;.\evosuite-standalone-runtime-1.0.6.jar;.\junit-4.12.jar;.\hamcrest-core-1.3.jar;"   org.junit.runner.JUnitCore  com.u.g.KeyClient_ESTest

Thrown Exception:

    FAILURES!!!
    Tests run: 2,  Failures: 1

Can someone please help/guide me to resolve this? Thanks in advance.

Additional Info:

The test class is a singleton, which connects to the database using JDBC API to retrieve certain values.

Here is solution which worked for me. The solution was to generate test claasses with below cmd option

-Dsandbox_mode=OFF

Complete command to generate test classes is

C:\java8\jdk1.8.0_102\bin\java  -jar evosuite-master-1.0.6.jar -Dsandbox_mode=OFF -class com.u.g.KeyClient -projectCP ".\log4j.jar;.\ojdbc6.jar;.\commons-codec-1.3.jar;.\target\classes;"

The corresponding KeyClient_ESTest_scaffolding class will have RuntimeSetting to turn off sandbox

@BeforeClass 
public static void initEvoSuiteFramework() { 
org.evosuite.runtime.RuntimeSettings.className = "com.ultimatix.gdpr.KeyClient"; 
org.evosuite.runtime.GuiSupport.initialize(); 
org.evosuite.runtime.RuntimeSettings.maxNumberOfThreads = 100; 
org.evosuite.runtime.RuntimeSettings.maxNumberOfIterationsPerLoop = 10000; 
org.evosuite.runtime.RuntimeSettings.mockSystemIn = true; 
org.evosuite.runtime.RuntimeSettings.sandboxMode = org.evosuite.runtime.sandbox.Sandbox.SandboxMode.OFF; 
org.evosuite.runtime.sandbox.Sandbox.initializeSecurityManagerForSUT(); 
org.evosuite.runtime.classhandling.JDKClassResetter.init();
setSystemProperties();
initializeClasses();
org.evosuite.runtime.Runtime.getInstance().resetRuntime();

}

Hope it helps someone facing similar problem.
