It does seem vaguely reasonable to support any extra data.
Don't you want to also handle arbitrary byte arrays, if e.g. one the 16-bit
size fields overflows the extra data?
It looks to me like getExtraLen could return a negative number.
probably I should. The webrev has been updated to simply
copy the rest of the extra data, if the "sz" is either < 0 or
out of the range.

And put a SPACE after "if".
updated.

Hi,
Please help review the change for #8023713
http://cr.openjdk.java.net/~sherman/8023713/webrev
<http://cr.openjdk.java.net/%7Esherman/8023713/webrev>
The root cause is that the newly introduced ZOS.writeExtra() (for
#8015666) fails to handle "irregular" extra data field. The zip spec
requires the the extra data stars with 4 bytes of "tag + size" pair
and then followed by the actual "extra data". The "offending" zip
file actually has the "irregular" extra data field with 1 single byte
as the extra data. That said, the implementation (ZOS) should still
be able handle this kind of zip entry correctly and appropriately.
The proposed solution is to simply copy the specified extra data
into the output stream.
Thanks!
