Wish : method unaccent. MutableBigDecimal and MutableBigInteger. StringEscaper.escapeXml() escapes characters > 0x7f. Depend on JDK 1.5+. ArrayUtils - add isNotEmpty() methods ArrayUtils - add nullToEmpty() methods CharRange - provide an iterator that lets you walk the chars in the range CharRange - add more readable static builder methods ClassUtils - new isAssignable() methods with autoboxing ClassUtils - add support to getShortClassName and getPackageName for arrays DateUtils - add ceiling() method DateUtils - add parseDateStrictly() method EqualsBuilder - add reset() method NumberUtils - add toByte() and toShort() methods Mutable numbers - add string constructors MutableBoolean - add toBoolean(), isTrue() and isFalse() methods StrBuilder - add appendSeparator() methods with an alternative default separator if the StrBuilder is currently empty SystemUtils - add IS_OS_WINDOWS_7 constant SystemUtils - add IS_JAVA_1_7 constant for JDK 1.7 StringUtils - add abbreviateMiddle() method StringUtils - add indexOfIgnoreCase() and lastIndexOfIgnoreCase() methods StringUtils - add isAllUpperCase() and isAllLowerCase() methods StringUtils - add lastOrdinalIndexOf() method to complement the existing ordinalIndexOf() method StringUtils - add repeat() method StringUtils - add startsWithAny() method StringUtils - add upperCase(String, Locale) and lowerCase(String, Locale) methods New Reflection package containing ConstructorUtils, FieldUtils, MemberUtils and MethodUtils ArrayUtils - addAll() does not handle mixed types very well CharSet - Synchronizing the COMMON Map so that getInstance doesn't miss a put from a subclass in another thread ClassUtils - improving performance of getAllInterfaces ClassUtils - toClass() throws NullPointerException on null array element DateUtils - Fix parseDate() cannot parse ISO8601 dates produced by FastDateFormat DateUtils - round() doesn't work correct for Calendar.AM_PM DateUtils - improve tests Entities - multithreaded initialization Entities - missing final modifiers; thread-safety issues EnumUtils - getEnum() doesn't work well in 1.5+ ExceptionUtils - use immutable lock target ExtendedMessageFormat - OutOfMemory with a pattern containing single quotes FastDateFormat - call getTime() on a calendar to ensure timezone is in the right state FastDateFormat - Remove unused field LocaleUtils - Initialization of available locales in LocaleUtils can be deferred NumberUtils - createNumber() thows a StringIndexOutOfBoundsException when only an "l" is passed in NumberUtils - isNumber(String) and createNumber(String) both modified to support '2.' StringUtils - improve handling of case-insensitive Strings StringUtils - replaceEach() no longer NPEs when null appears in the last String[] StringUtils - correct JavaDocs for startsWith() and startsWithIgnoreCase() StringEscapeUtils - escapeJava() escapes '/' characters StringEscapeUtils - change escapeJavaStyleString() to throw UnhandledException instead swallowing IOException and returning null WordUtils - fix StringIndexOutOfBoundsException when lower is greater than the String length StrBuilder - Performance improvement by doubling the size of the String in ensureCapacity Compare, Equals and HashCode builders - use ArrayUtils to avoid creating a temporary List EqualsBuilder - removing the special handling of BigDecimal (LANG-393) to use compareTo instead of equals because it creates an inequality with HashCodeBuilder HashCodeBuilder - Performance improvement: check for isArray to short-circuit the 9 instanceof checks HashCodeBuilder - Changing the hashCode() method to return toHashCode() HashCodeBuilder - reflectionHashCode() can generate incorrect hashcodes HashCodeBuilder and ToStringStyle - use of ThreadLocal causes memory leaks in container environments ToStringBuilder - make default style thread-safe RandomUtils - nextLong() always produces even numbers RandomUtils - RandomUtils tests are failing frequently ClassUtils.getShortClassName(String) inefficient Shouldn't Commons Lang's StringUtils have a "common" string method?
