The class belongs to one of the packages EvoSuite cannot currently handle

[m-zakeri]

Context

EvoSuite cannot generate tests for most of the classes in some Java projects, for instance, the Apache Xerces

Steps to Reproduce

For all classes in the Apache xerces2-j-trunk project, EvoSuite fails to generate tests.

EvoSuite Arguments

java -jar evosuite.jar -projectCP ./build/classes -class org.apache.xerces.util.URI

Current Result

• EvoSuite 1.0.6
• Going to generate test cases for class: org.apache.xerces.util.URI [MASTER] 12:06:10.306 [main] ERROR EvoSuite - Fatal crash on main EvoSuite process. Class using seed 1621496170302.

EvoSuite has some issues with Xerces that we don't fully understand, hence this is deactivated. I have now enabled testing of Xerces classes in 9c7b31994bf65079272fa3e5d80cacd8eed13a66; it doesn't work well, and there are some individual classes where EvoSuite will just crash. But for many others it will generate tests.
