* Changes in recent builds that maybe of interest:

o Build 22
+ *JDK-8266369: New implementation of
java.nio.channels.Selector on Microsoft Windows. *
o Build 21
+ *JDK-8196415: JARs signed with SHA-1 algorithms are
restricted by default.*
+ *JDK-8266858: macOS on ARM early access available.*
# The ARM port should behave similarly to the Intel port.
There are no known feature differences.
# When reporting issues on macOS please specify if using
ARM or x64.
*We need your help in testing new Selector implementation on Windows [1]:*
* The implementation of the Selector API on Windows has been replaced
in JDK 17 b22 with a new more scalable implementation [2].
* The old select based Selector implementation has been the default
since Java 1.4 (2002) so replacing it is a significant change.
* It would be really helpful to get more testing of the new
implementation before the fork for Rampdown Phase One on June 10th.
*Other Topics which might be of Interest:*
* Updates to JEP 411: Deprecate the Security Manager for Removal |
