Hi Sherman,
flag0 javadoc:
/**
957 * The pattern flags used during compiling. The flags might be
turn*ed* on and
958 * off by*an *embedded flag.
959 */
2946-3047: Can an exception happen between save and restore? Would the
value of flag0 matter if so?
+Copyright year update
Regards, Roger

Hi,
Please help review the change for JDK-8194667
issue: https://bugs.openjdk.java.net/browse/JDK-8194667
webrev: http://cr.openjdk.java.net/~sherman/8194667/webrev
The bits of "flags" are being updated on and off during the pattern
compiling by
the possible embedded match flag(s) in old implementation. The
proposed fix is
to add a temporary field "flags0" for this purpose and save/store
"flags" for the
purpose of deserialization (same as the field "pattern").
For the compatibility concern I'm leaving the behavior of method
flags() unchanged
to return the muted "flags". Arguably it might be desired to return
the original "flags"
instead. We can leave this "issue" for future RFE.
1145 public int flags() {
1146 return flags0;
1147 }
Thanks,
Sherman
