A DESCRIPTION OF THE PROBLEM :
We generated a test case automatically. And it failed with dead cycle in com.sun.tools.corba.se.idl.toJavaPortable.Util.sansArrayInfo("[").
Although this method is no longer available in jdk11, it still affects people who use jdk8.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The test case is :
@Test
    public void test_sansArrayInfo(){
        String string0 = "[";
        com.sun.tools.corba.se.idl.toJavaPortable.Util.sansArrayInfo(string0);
    }

ACTUAL -
dead cycle

---------- BEGIN SOURCE ----------
static public String sansArrayInfo (String name)
  {
    int index = name.indexOf ('[');
    if (index >= 0)
    {
      String array = name.substring (index);
      name = name.substring (0, index);
      while (!array.equals (""))
      {
        name = name + "[]";
        array = array.substring (array.indexOf (']') + 1);
      }
    }
    return name;
