------------------------------------------------------------
i run on https and in my case read returns 1, so not whole 2K is buffered into
byte array and from java doc
https://docs.oracle.com/javase/7/docs/api/java/io/InputStream.html#read(byte[])
there is no guarantee that whole buffer will be read. moreover read can returns
-1 and IOUtils.newStringFromBytes will fail if that happens. you assume that
read will return whole 2K, for example

there is no guarantee that whole buffer will be read. moreover read can returns
-1 and IOUtils.newStringFromBytes will fail if that happens. current code could
be rewritten into this same bad impl:
byte buf[] = new byte[2048];
in.read(buf);
String msg = IOUtils.newStringFromBytes(buf, 0, 2048);
in.unread(buf, 0, 2048);
because you assume that read will return whole 2K, for example

> Key: CXF-7025
> URL: https://issues.apache.org/jira/browse/CXF-7025
> Project: CXF
> Issue Type: Bug
> Components: Core, JAX-RS
> Affects Versions: 3.1.4
> Reporter: Petr Havlena
>
> in method AttachmentDeserializer.findBoundaryFromInputStream line: "int i =
> in.read(buf)" is invalid, because read returns "some number of bytes from the
> input stream and stores them into the buffer array b" so you should check
> result from read method and repeat reading if neccesary
