Hello~
In order to generate test case ,in progress jpf-symbc, I run the jpf : strings.HelloWorld.jpf.
In results, I can't get the test case ,but only search start.
So, can SPF support test case generation for string input?the output as follows:
[WARNING] unknown classpath element: /home/zhou/PROJECTS/tmp/jpf2/jpf-core/build/jpf-classes.jar
