Do we assume searchChar is usually relatively small; // If so then calling toString() on it is better than reverting to // the green implementation in the else block return ((String) cs).indexOf((String) searchChar, start); } else { 64
Implement rather than convert to String return cs.toString().indexOf(searchChar.toString(), start); } 69

org.apache.commons.lang3.CharSequenceUtils Line
- we must do a forward traversal for this to avoid duplicating code points 265
org.apache.commons.lang3.ClassUtils Line
From v2.2, this method handles {@code Void.TYPE}, returning {@code Void.TYPE}. </p> 1558
org.apache.commons.lang3.StringUtils Line
This method changed in 2.0. It now more closely matches Perl chomp. </p> 662
This method changed in version 2.0. It now more closely matches Perl chomp. For the previous behavior, use {@link #substringBeforeLast(String, String)}. This method uses {@link String#endsWith(String)}. </p> 709
LINT this intentionally uses == to allow for both null 862
LINT this intentionally uses == to allow for both null 963
This method changed in Lang version 2.0. It no longer trims the CharSequence. That functionality is available in isBlank(). </p> 3537

LINT str cannot be null here 8097
This method changed in Lang version 2.0. It no longer performs a word based algorithm. If you only use ASCII, you will notice no change. That functionality is available in org.apache.commons.lang3.text.WordUtils. </p> 8620
org.apache.commons.lang3.builder.EqualsBuilder Line
we cannot store the actual objects in a HashSet, as that would use the very hashCode() we are in the process of calculating. 99
org.apache.commons.lang3.builder.HashCodeBuilder Line
we cannot store the actual objects in a HashSet, as that would use the very hashCode() we are in the process of calculating. 125
This method uses >> and not >>> as Effective Java and Long.hashCode do. Ideally we should switch to >>> at some stage. There are backwards compat issues, so that will have to wait for the time being. See LANG-342. 732
org.apache.commons.lang3.builder.ToStringStyle Line
It assumes that the toString has been created from the same ToStringStyle. </p> 1730
