Ivan Ponomarev closed TEXT-239.
-------------------------------
> TextStringBuilder.append(char[], int, int) uses wrong variable in startIndex
> exception message
> ----------------------------------------------------------------------------------------------
>
> Key: TEXT-239
> URL: https://issues.apache.org/jira/browse/TEXT-239
> Project: Commons Text
> Issue Type: Bug
> Reporter: Ivan Ponomarev
> Priority: Trivial
> Fix For: 1.15.1
>
>
> {{TextStringBuilder.append(final char[] chars, final int startIndex, final
> int length)}} throws {{StringIndexOutOfBoundsException}} when {{startIndex}}
> is invalid, but the exception message incorrectly prints {{length}} instead
> of {{startIndex}}:
> {code:java}
> if (startIndex < 0 || startIndex > chars.length) {
> throw new StringIndexOutOfBoundsException("Invalid startIndex: " +
> length);
> }
> {code}
> This appears to be a copy/paste issue (same bug exists in the deprecated
> {{StrBuilder}} variants).
> h4.Proposed Fix
> Change the thrown message to use the correct variable:
> {code:java}
> throw new StringIndexOutOfBoundsException("Invalid startIndex: " +
> startIndex);
> {code}
> h4.Also affected
> * deprecated `org.apache.commons.text.StrBuilder`
> * deprecated `org.apache.commons.lang3.text.StrBuilder`
