A recent fix was introduced to preserve the behaviour of an old buggy implementation of smartcardio Card.disconnect :
https://bugs.openjdk.java.net/browse/JDK-8049250

The old behaviour is not fully restored with this flag if a security manager lacking sufficient permissions is present. This could disrupt legacy applications which may wish to rely on the old behaviour. Some internal testing has also highlighted this.

To enhance the 8049250 fix, I'm proposing we delay the boolean flip operation until post the security check.

Bug report is not public due to internal links and servers being present in description.

I'd like to get this into JDK 9 and 8u20.

regards,
Sean.
