> TextStringBuilder equals method changed behaviour from 1.8 to 1.9
> -----------------------------------------------------------------
>
> Key: TEXT-211
> URL: https://issues.apache.org/jira/browse/TEXT-211
> Project: Commons Text
> Issue Type: Bug
> Affects Versions: 1.9
> Reporter: Nikolaos Georgiou
> Priority: Major
> Time Spent: 4h 40m
> Remaining Estimate: 0h
>
> We found a regression (or breaking compatibility change) in the
> TextStringBuilder equals method when upgrading commons-text from 1.8 to 1.9
>
> The 1.8 version (
> [https://github.com/apache/commons-text/blob/commons-text-1.8/src/main/java/org/apache/commons/text/TextStringBuilder.java#L2915]
> ) would only compare the parts of the buffer that fall within the range
> 0..size.
> The 1.9 version (
> [https://github.com/apache/commons-text/blob/rel/commons-text-1.9/src/main/java/org/apache/commons/text/TextStringBuilder.java#L1855]
> ) compares the entire buffer arrays.
> If a TextStringBuilder has extra capacity in the buffer, comparison fails.
