Hi Alan, here is output:
level:0, strategy: 2, dowrap: true
is finished: true
is finished: true
is finished: true
is finished: true
is finished: true
level:1, strategy: 0, dowrap: false
is finished: false
m=525312, n=497972, len=524288, eq=false
STDERR:
java.lang.RuntimeException: De/inflater failed:java.util.zip.Deflater@23a0858b
But I guess this behaviour could be explained (by zEDC). On s390x, there is
additional instruction present and it could be enabled by setting `DFLTCC=1`.
And for accelerator the size of compressed data could go`2 times` the size of
actual data. Again this is not deterministic as well, i.e. for same data there
could be different valid deflate stream.
