A DESCRIPTION OF THE PROBLEM :
The test case failed with StringIndexOutOfBoundsException.
We should judge whether parameter of substring is in legal range before calling substring method.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The test case is :
@Test
    public void test_resolveEntity_1_1(){
        String string1 = " ";
        String string2 = " <>";
        com.sun.rowset.internal.XmlResolver xmlResolver0 = new com.sun.rowset.internal.XmlResolver();
        xmlResolver0.resolveEntity(string1, string2);
    }

ACTUAL -
java.lang.StringIndexOutOfBoundsException: String index out of range: -1

at java.lang.String.substring(String.java:1927)
at com.sun.rowset.internal.XmlResolver.resolveEntity(XmlResolver.java:42)

---------- BEGIN SOURCE ----------
    public InputSource resolveEntity(String var1, String var2) {
        String var3 = var2.substring(var2.lastIndexOf("/"));
        return var2.startsWith("http://java.sun.com/xml/ns/jdbc") ? new InputSource(this.getClass().getResourceAsStream(var3)) : null;
    }
---------- END SOURCE ----------
