JDK 7 preview is available: http://jdk7.java.net/
Have done a small amount of testing with Java 7 and find encouraging results for application performance particularly with the new Garbage First garbage collector -XX:+UseG1GC in place of the usual -XX:+UseParallelGC garbage collector. Donât let the new collector scare you the ParallelGC we all use and love still works with Java 7. Once JDK 7 is installed, edit CF\runtime\bin\jvm.config (backup the original first) eg: java.home=C:\\Program Files\\Java\\jdk1.7.0\\jre # Arguments to VM java.args=-server -Xmx512m -Dsun.io.useCanonCaches=false -XX:MaxPermSize=192m -XX:+UseG1GC etc For those interested my CFADMIN > System Information reports in part: Server Details Server Product ColdFusion Version 9,0,1,274733 Edition Developer Update Level /C:/ColdFusion9/lib/updates/chf9010001.jar Adobe Driver Version 4.0 (Build 0005) JVM Details Java Version 1.7.0-ea Java Vendor Oracle Corporation Java Vendor URL http://java.oracle.com/ Java Home C:\Program Files\Java\jdk1.7.0\jre User Dir C:\ColdFusion9\runtime\bin Java VM Specification Version 1.7 Java VM Specification Vendor Oracle Corporation Java VM Specification Name Java Virtual Machine Specification Java VM Version 21.0-b05 Java VM Vendor Oracle Corporation Java VM Name Java HotSpot(TM) Server VM Java Specification Version 1.7 Java Specification Vendor Oracle Corporation Java Specification Name Java Platform API Specification Java Class Version 51.0 Has anyone noticed something positive or negative with JDK 7 and CF? Caveat - do not try this at home kids (ie on production CF servers). Not much interest with this on other CF forum so thought would post here.
