ClassUtils.getShortClassName(String) inefficient Shouldn't Commons Lang's StringUtils have a "common" string method? FastDateFormat getDateInstance() and getDateTimeInstance() assume Locale.getDefault() won't change OSGi-ify Lang StrBuilder appendFixedWidth does not handle nulls infinite loop in Fraction.reduce when numerator == 0 FastDateFormat thread safety ClassUtils.getShortClassName and ClassUtils.getPackageName and class of array LocaleUtils.toLocale() rejects strings with only language+variant Enum is not thread-safe BooleanUtils.toBoolean() - invalid drop-thru in case statement causes StringIndexOutOfBoundsException ArrayUtils.toClass Why does appendIdentityToString return null? NumberUtils.min(floatArray) returns wrong value if floatArray[0] happens to be Float.NaN Dates.round() behaves incorrectly for minutes and seconds StringUtils.length(String) returns null-safe length adding a StringUtils.replace method that takes an array or List of replacement strings Adding functionality to DateUtils to allow direct setting of various fields. Add escaping for CSV columns to StringEscapeUtils StringUtils: startsWith / endsWith / startsWithIgnoreCase / endsWithIgnoreCase / removeStartIgnoreCase / removeEndIgnoreCase methods Extension to ClassUtils: Obtain the primitive class from a wrapper Javadoc bugs - cannot find object Optimize HashCodeBuilder.append(Object) http://commons.apache.org/lang/developerguide.html "Building" section is incorrect and incomplete Ambiguous / confusing names in StringUtils replace* methods Add new splitByWholeSeparatorPreserveAllTokens() methods to StringUtils Add getStartTime to StopWatch Perhaps add containsAny() methods? Javadoc Example for EqualsBuilder is questionable EqualsBuilder don't compare BigDecimals correctly Split camel case strings Add Calendar flavour format methods to DateFormatUtils Calculating A date fragment in any time-unit Memory usage improvement for StringUtils#getLevenshteinDistance() Add ExtendedMessageFormat to org.apache.commons.lang.text StringEscapeUtils.escapeJavaScript() method did not escape '/' into '\/', it will make IE render page uncorrectly Add toArray() method to IntRange and LongRange classes add SystemUtils.IS_OS_WINDOWS_VISTA field Pointless synchronized in ThreadLocal.initialValue should be removed ToStringStyle javadoc should show examples of styles Documentation bug for ignoreEmptyTokens accessors in StrTokenizer BooleanUtils toBooleanObject javadoc does not match implementation truncateNicely method which avoids truncating in the middle of a word Use of enum prevents a classloader from being garbage collected resuling in out of memory exceptions. NumberUtils.max(byte[]) and NumberUtils.min(byte[]) are missing Null-safe comparison methods for finding most recent / least recent dates. StopWatch: suspend() acts as split(), if followed by stop() StrBuilder.replaceAll and StrBuilder.deleteAll can throw ArrayIndexOutOfBoundsException. Bug in method appendFixedWidthPadRight of class StrBuilder causes an ArrayIndexOutOfBoundsException ToStringBuilder throws StackOverflowError when an Object cycle exists Create more tests to test out the +=31 replacement code in DurationFormatUtils. StrBuilder contains usages of thisBuf.length when they should use size Enum JavaDoc: 1) outline 5.0 native Enum migration 2) warn not to use the switch() , 3) point out approaches for persistence and gui Wrong behavior of Entities.unescape NumberUtils.createNumber throws NumberFormatException for one digit long NullPointerException in isAvailableLocale(Locale) FastDateFormat.mRules is not transient or serializable StringUtils.join should allow you to pass a range for it (so it only joins a part of the array) Refactor Entities methods Tests fail to pass when building with Maven 2 DurationFormatUtils returns wrong result unescapeXml("&12345678;") should be "&12345678;" Optimize StringEscapeUtils.unescapeXml(String) BooleanUtils isNotTrue/isNotFalse Extra StrBuilder methods Add a pair of StringUtils.substringsBetween;String[] methods HashCodeBuilder throws java.lang.StackOverflowError when an object contains a cycle. Wish for StringUtils.join(Collection, *) StrBuilderTest#testReplaceStringString fails.
