> A review of the utilities in camel-util (and their callers in camel-support)
> found these bugs:
> # *URISupport.createQueryString* with an empty list value writes an extra
> {{&}} ({{a=1&&c=2}}, or a trailing {{&}} when it is last).
> # *URISupport.parseQuery* adds a parameter with an empty name for a double
> {{&}} ({{a=1&&b=2}}), so {{timer:a?period=1000&&delay=1}} fails with a
> cryptic {{Index 0 out of bounds}} error.
> # *FileUtil.stripExt("/.bashrc")* returns {{/}} (a hidden file in the root
> lost its name).
> # *FileUtil.compactPath("C:/a/../../b")* returns {{b}}, the {{..}} removes
> the windows drive.
> # *IOHelper.getCharsetNameFromContentType* matches a parameter that ends with
> {{charset=}}, so {{text/plain; mycharset=foo; charset=iso-8859-1}} returns
> {{foo}}.
> # *IOHelper.EncodingInputStream* turns a surrogate pair (such as an emoji)
> that is split at the end of its 4096 char buffer into {{??}}.
> # *TimeUtils.toMilliSeconds* silently returns 0 or a partial value for an
> invalid time pattern. As this is used for every numeric endpoint/component
> option, {{timer:a?period=five}} gives a period of 0, {{period=1m30}} gives
> 60000, {{period=5S}} gives 0 (the catalog accepts the upper case unit),
> {{period=-5s}} gives 0 (while {{-500ms}} gives -500), and {{"s"}} throws
> StringIndexOutOfBoundsException.
> # A time pattern too large for an {{int}} option overflows ({{25d}} becomes
> {{-2134967296}}) in PropertyConfigurerSupport and LanguageSupport.
> # *Scanner.hasNext()* returns true and then *next()* throws
> NoSuchElementException when a delimiter that can grow (such as {{\s*;\s*}})
> is split at the end of its buffer at the end of the input (tokenize with
> {{regex=true}}).
> # *StringHelper.normalizeWhitespace* (the Simple {{normalizeWhitespace}}
> function) only collapses runs of spaces, so {{a \t b}} and {{a\t\tb}} are
> unchanged.
> # *EndpointUriFactorySupport.buildPathParameter* replaces the wrong text when
> the name of a path parameter is also part of another name, such as
> {{knative:type/typeId}} which builds {{knative:type/channelId}} instead of
> {{knative:channel/foo}}. The value is also used as a regular expression
> replacement, so {{C:\dir}} becomes {{C:dir}} and {{p$1}} fails. The same for
> *StringHelper.replaceFromSecondOccurrence*, which also only replaced every
> other occurrence.
> # *StringHelper.dashToCamelCase* with skipQuotedOrBracket stops protecting
> keys in {{[...]}} after any quoted section, so
> {{camel.foo['a'].bar[x-y].my-opt}} gives {{bar[xY]}}.
> # *StringHelper.removeStartingCharacters* throws
> StringIndexOutOfBoundsException for an empty text or when all characters
> match (such as {{jms:queue:/}}).
> # *BackOffTimerTask*: the delay grows above {{maxDelay}} (with a multiplier)
> and stays there, and after *reset()* every delay is 0.
> # *ObjectHelper.getException* (and createExceptionIterable) loops forever and
> runs out of memory when the cause chain has a cycle (used by onException and
> doCatch).
> # *ObjectHelper.loadClass* cannot load primitive arrays ({{int[]}}), short
> name wrapper arrays ({{Integer[]}}) or multi dimensional arrays
> ({{String[][]}}).
> # *AnnotationHelper.findMethodsWithAnnotation* returns bridge methods and the
> overridden method of the super class too, so camel-flink calls a callback
> twice and camel-jpa fails with "Only one method can be annotated" for an
> entity that overrides an annotated callback.
> # *ThreadPoolRejectedPolicy.Block* silently drops a task when the pool is
> shutdown (the task is not rejected, so the exchange never completes).
> Not changed:
> * URISupport.normalizeUri does not give the same uri when a normalized uri is
> normalized again (the fast and the complex path encode the query differently
> since CAMEL-24524). Fixing it changes the encoding of existing endpoint uris,
> so it needs a decision of its own.
> * StringQuoteHelper.splitSafeQuote trims quoted values that are not last -
> the file is changed by CAMEL-25081.
> * BaseOrderedProperties (OrderedLocationProperties) does not override
> forEach, getOrDefault, putIfAbsent, compute, merge and more, so camel-main
> does not log the "Property not auto-configured" warnings. Fixing forEach
> needs a change in camel-main at the same time (consumed camel.variable keys
> are not removed), so this is left for a separate ticket.
> * ObjectHelper in camel-support (type coercion and iterators) is handled in a
> separate ticket.
