Commons Lang is a set of utility functions and reusable components that should be of use in any Java environment. INCOMPATIBLE CHANGES WITH VERSION 2.2: - Calling stop on a suspended StopWatch will no longer change the underlying time. It's very unlikely anyone was relying on that bug as a feature. ADDITIONAL INCOMPATIBLE CHANGES WITH VERSION 2.0: - The Nestable interface defines the method indexOfThrowable(Class). Previously the implementations checked only for a specific Class. Now they check for subclasses of that Class as well. For most situations this will be the expected behavior (i.e. it's a bug fix). If it causes problems, please use the ExceptionUtils.indexOfThrowable(Class) method instead. Note that the ExceptionUtils method is available in v1.0 and v2.0 of commons-lang and has not been changed. (An alternative to this is to change the public static matchSubclasses flag on NestableDelegate. However, we don't recommend that as a long-term solution.) - The StopWatch class has had much extra validation added. If your code previously relied on unusual aspects, it may no longer work. - Starting with version 2.1, Ant version 1.6.x is required to build. Copy junit.jar to ANT_HOME/lib. You can get JUnit from https://www.junit.org. See the developer's guide for more details. DEPRECATIONS FROM 2.2 to 2.3: - None DEPRECATIONS FROM 2.1 to 2.2: - None DEPRECATIONS FROM 2.0 to 2.1: - The enum package has been renamed to enums for JDK 1.5 compliance. All functionality is identical, just the package has changed. This package will be removed in v3.0. - NumberUtils.stringToInt - renamed to toInt - DateUtils - four constants, MILLIS_IN_* have been deprecated as they were defined as int not long. The replacements are MILLIS_PER_*. BUG FIXES IN 2.3: * [LANG-69 ] - ToStringBuilder throws StackOverflowError when an Object cycle exists * [LANG-102] - Refactor Entities methods * [LANG-153] - Can't XMLDecode an Enum * [LANG-262] - Use of enum prevents a classloader from being garbage collected resulting in out of memory exceptions. * [LANG-279] - HashCodeBuilder throws java.lang.StackOverflowError when an object contains a cycle. * [LANG-281] - DurationFormatUtils returns wrong result * [LANG-286] - Serialization - not backwards compatible * [LANG-292] - unescapeXml("&12345678;") should be "&12345678;" * [LANG-294] - StrBuilder.replaceAll and StrBuilder.deleteAll can throw ArrayIndexOutOfBoundsException. * [LANG-295] - StrBuilder contains usages of thisBuf.length when they should use size * [LANG-299] - Bug in method appendFixedWidthPadRight of class StrBuilder causes an ArrayIndexOutOfBoundsException * [LANG-300] - NumberUtils.createNumber throws NumberFormatException for one digit long * [LANG-303] - FastDateFormat.mRules is not transient or serializable * [LANG-304] - NullPointerException in isAvailableLocale(Locale) * [LANG-313] - Wrong behavior of Entities.unescape * [LANG-315] - StopWatch: suspend() acts as split(), if followed by stop() IMPROVEMENTS IN 2.3: * [LANG-258] - Enum Javadoc * [LANG-266] - Wish for StringUtils.join(Collection, *) * [LANG-268] - StringUtils.join should allow you to pass a range for it (so it only joins a part of the array) * [LANG-275] - StringUtils substringsBetween * [LANG-282] - Create more tests to test out the +=31 replacement code in DurationFormatUtils. * [LANG-287] - Optimize StringEscapeUtils.unescapeXml(String) * [LANG-289] - NumberUtils.max(byte[]) and NumberUtils.min(byte[]) are missing * [LANG-291] - Null-safe comparison methods for finding the most recent / least recent dates. * [LANG-306] - StrBuilder appendln/appendAll/appendSeparator * [LANG-310] - BooleanUtils isNotTrue/isNotFalse * [LANG-314] - Tests fail to pass when building with Maven 2
