Early Access builds of JDK 8u76 b04, JDK 9 & JDK 9 with Project Jigsaw b104 are available on java.net

Hi All,

Early Access b04 for JDK 8u76 is available on java.net, summary of  changes are listed here .

Early Access b104 for JDK 9 is available on java.net, summary of  changes are listed here .

JEP 280: Indify String Concatenation [0]

This JEP proposed to change the static String-concatenation bytecode sequence generated by javac to use invokedynamic calls to JDK library functions. This will enable future optimizations of String concatenation without requiring further changes to the bytecode emitted by javac.

Early Access b104 for JDK 9 with Project Jigsaw is available on java.net.

Great to meet so many of you at FOSDEM this year,  videos of some of the presentations are available [1]

Rgds,Rory
