Number of occurrences found in the code: 57

org.apache.commons.lang3.AbstractLangTest Line
Do more to make sure memory is not retained, maybe like Log4j checks for it. 35
org.apache.commons.lang3.ArraySorter Line
For 4.0, rename to ArraySort, since we cover the sort() method here, see also ArrayFill. 25
org.apache.commons.lang3.CharRange Line
This is no longer public and will be removed later as CharSet is moved to depend on Range. 32
org.apache.commons.lang3.CharSequenceUtils Line
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

I think this should hold, needs further investigation String unescapedFromEntity = StringEscapeUtils.unescapeHtml4("𝍢"); assertEquals("High Unicode should have been unescaped", original, unescapedFromEntity); 205

org.apache.commons.lang3.reflect.FieldUtils Line
is this workaround still needed? lang requires Java 6 Sun Java 1.3 has a bugged implementation of getField hence we write the code ourselves 181

Noteable Markers

Number of occurrences found in the code: 20

org.apache.commons.lang3.CharSequenceUtils Line
- we must do a forward traversal for this to avoid duplicating code points 265
org.apache.commons.lang3.CharSet Line
This is no longer public as CharRange is no longer a public class. It may be replaced when CharSet moves to Range. 256
org.apache.commons.lang3.ClassUtils Line
From v2.2, this method handles {@code Void.TYPE}, returning {@code Void.TYPE}. </p> 1483
org.apache.commons.lang3.StringUtils Line
This method changed in 2.0. It now more closely matches Perl chomp. </p> 655
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> 702
LINT this intentionally uses == to allow for both null 855
LINT this intentionally uses == to allow for both null 956
This method changed in Lang version 2.0. It no longer trims the CharSequence. That functionality is available in isBlank(). </p> 3529
logic duplicated below START 6435
logic mostly below END 6450
logic mostly duplicated above START 6489
logic duplicated above END 6504
LINT str cannot be null here 8071
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> 8592
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. 124
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. cf LANG-342. 731
org.apache.commons.lang3.text.ExtendedMessageFormatTest Line
FAILING - currently sub-formats not supported 134
FAILING - currently sub-formats not supported 151
org.apache.commons.lang3.time.StopWatch Line
As from v2.1, the methods protect against inappropriate calls. Thus you cannot now call stop before start, resume before suspend or unsplit before split. </p> 51
