---------------------------------------
Summary: NIOConverter File to ByteBuffer conversion behavior is
potentially non-deterministic
Key: CAMEL-19975
URL: https://issues.apache.org/jira/browse/CAMEL-19975
Project: Camel
Issue Type: Bug
Reporter: James Netherton
Maybe a bit of an edge case, but the result of
{{NIOConverter.toByteBuffer(File)}} can potentially vary depending on the size
of the file used for conversion. It can be {{null}} or a {{ByteBuffer}} with
partial or empty content.
The converter does:
{code:java}
byte[] buf = new byte[(int) file.length()];
{code}
If {{file.length()}} > {{Integer.MAX_VALUE}}, then the cast from {{long}} to
{{int}} can produce some unexpected results. E.g if the file size is
{{Integer.MAX_VALUE + 1}}, then the result from the cast is {{-2147483648}}. If
the file size is {{4294967296}} then the result from the cast is {{0}}.
