[New-bugs-announce] [issue5701] ZipFile returns compressed data stream when encountering unsupported compression method

[Yngve AAdlandsvik]

New submission from Yngve AAdlandsvik <ymgve at start.no>:

The attached .zip archive contains two uncompressed files (2!
SCHEME.Z64, 3!SCHEME.Z64) and two files compressed with IMPLODE (1!
SCHEME.Z64, 4!SCHEME.Z64), a compression method not currently supported 
in ZipFile.

When using ZipFile.read() on the latter files, the compressed data 
stream is returned, while I assume the proper response would be to 
throw an exception of some kind to signal that the method is 
unsupported.
