Ivan Ponomarev created TEXT-239:
-----------------------------------
Summary: 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
{{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`
