TargetLengthBasedClassNameAbbreviator does not work for strings with more than 12 dots (inclusive).
---------------------------------------------------------------------------------------------------

                 Key: LBCLASSIC-110
                 URL: http://jira.qos.ch/browse/LBCLASSIC-110
             Project: logback-classic
          Issue Type: Bug
          Components: appender
    Affects Versions: 0.9.9, 0.9.10, 0.9.11, 0.9.12, 0.9.13, 0.9.14, 0.9.15
            Reporter: Lukas Zapletal
            Assignee: Logback dev list


Please add this to TargetLengthBasedClassNameAbbreviatorTest:

    System.out.println("13");
    {
      // 13 dots test
      TargetLengthBasedClassNameAbbreviator abbreviator = new TargetLengthBasedClassNameAbbreviator(20);
      String name = "com.pike.test.puma.wm.isd2dita.core.g.project.server.pkg.isobjecttype.isobject.ISObjectContentGenerator";
      assertEquals("c.p.t.p.w.i.c.g.o.s.r.i.ISObjectContentGenerator", abbreviator.abbreviate(name));
    }

    System.out.println("12");
    {
      // 12 dots test
      TargetLengthBasedClassNameAbbreviator abbreviator = new TargetLengthBasedClassNameAbbreviator(20);
      String name = "com.pike.puma.wm.isd2dita.core.g.project.server.pkg.isobjecttype.isobject.ISObjectContentGenerator";
      assertEquals("c.p.p.w.i.c.g.o.s.r.i.ISObjectContentGenerator", abbreviator.abbreviate(name));
    }

Logs are disappearing when this bug occurs. It throws ArrayIndexOfBounds when testing but in production logs are just skipped (thus this bug is not FATAL-CRITICAL).

Workaround: higher the 12 dot limit.

Better workaround: handle with strings correctly not to ses AIOB exception ever.
