> [TextBasedReader|https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/TextSource.java#L88]
> is backed by a TextSource, which may have a start and end offset. If the end
> offset does not correspond to a delimiter, the TextBasedReader will not
> respect the end offset and will instead read past the end offset to the next
> instance of a delimiter. See
> [TextBasedReader#findDelimiterBounds|https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/TextSource.java#L176]
> which finds the end of the next record to read: this method will "consume
> the channel till either EOF or the delimiter bounds are found." I believe
> this is a bug and that this method should also check for the end offset, not
> just EOF or a delimiter.
