Reinhold Publishes Open Letter to JCP Pleading That JPMS (Jigsaw) Is Approved
Mark Reinhold has published an open letter to the JCP Executive Committee. In the letter he expresses surprise that IBM has decided to vote against the JSR, and argues that RedHat’s decision to vote "no" is motivated by a desire to "preserve and protect their home-grown, non-standard module system, which is little used outside of the JBoss/Wildfly ecosystem".

IBM and Red Hat to Vote "No" on Java Modules (Jigsaw)
InfoQ has previously reported on the developing situation regarding JSR 376 - the Java Platform Module System, commonly called "Project Jigsaw". Now, in a highly unusual move, IBM and Red Hat have both publicly announced that they will vote "no" on Jigsaw in its current form.

Object Deserialisation Filters Backported from Java 9
JEP 290, which allows filtering of incoming data when deserialising an object, and was initially targeted to Java 9, has been backported to Java 6, 7, and 8. The feature provides a mechanism to filter incoming data in an object input stream as it is being processed, and can help prevent deserialisation vulnerabilities like the one that affected Apache Commons and other libraries a while back.

Date and Time Formatting in Java 9 Will Get Closer to Unicode Locale Standards
Several parsing and formatting changes have been incorporated to bring the functionality closer to Unicode Locale Data Markup Language (LDML). These changes have been supervised by Stephen Colebourne, creator of the popular library JodaTime, precursor of the new java.time component in Java 8. Abiding by the Unicode standard will provide better interoperability with other non-Java systems.

Java 9 Enters First Bug Fixing Round
Java 9 is now officially feature complete, meaning the first bug-fixing phase has started. HTTP/2 Client didn't make it on time for the deadline and has been downgraded to an incubating feature. Since the objective now is to prepare Java 9 for general availability in July, it is very unlikely that any new JEP will be added at this point.

Latest Java 9 Schedule Appears to Be at Risk from the Outset
After approving the feature extension process, Oracle has confirmed July 2017 as release date for Java 9. Similar to a previous estimation by InfoQ, the new schedule involves a longer wait time for feature extension and impacted testing phases which may impose a risk. Early, informal testing might be in place to compensate.

Oracle's OpenJDK Cleanup of "Unsafe" Implementation
As Java 9 approaches general availability, many of the defining JEPs are starting to take final shape. JEP 260 (Encapsulate Most Internal APIs) proposes to expose the functionality of the controversial sun.misc.Unsafe class via variable handles, and a new posting to the JDK Bug tracker proposes further optimizations and cleanups for Unsafe.

Oracle Confirms G1 as Default Garbage Collector for Java 9
As previously mentioned on InfoQ, Oracle had proposed JEP 248, about making G1 the default garbage collector, to be included in the list of JEPs targeting Java 9; recently, Oracle has confirmed such decision and made it official. The decision triggered a lengthy debate in the HotSpot’s email discussion list, which concluded with a provision to defer the change if G1 proves not to be fully ready.
