Java class file corrupted during extract

[Jason Bacon <bacon4000%gmail.com@localhost>]

Can anybody explain this?

When installing wip/fastqc via pkgsrc, one of the Java programs fails 
with an internal error.  I found that the checksum on the class file is 
wrong when it's unpackedby pkgsrc, but correct if I unpack it manually 
using the same unzip command.

Thanks,
