Unable to run in JDK8

[smallufo]

I want to design the whole web app in Java 8

Here are the steps :

follow this page :

http://www.javacodegeeks.com/2013/02/multiple-java-jdks-on-your-macosx-environment.html

assign JAVA_HOME to JDK8's home

run java -version to make sure I am using JDK8

Modify the sample code : ApiController

add some lambda code in one method :

      List<String> versions = Arrays.asList("Java 7", "Java 8");

      versions.sort(String::compareTo);

      System.out.println("Language versions : " + versions);

In pom.xml

maven-compiler-plugin , source and target change to 1.8

run :

mvn jetty:run

first , it shows :

$ mvn jetty:run

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256m; support was removed in 8.0

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0

[INFO] Scanning for projects...

then , errors occur :

Is it hibernate's problem ?

[Raphael André Bauer]

Hi smallufo,


I have no idea - but the root cause seems to be javaassist - and
javaassist does bytecode manipulation. Maybe the lib is not yet
compatible with JDK8. In any case JDK8 is a pre release version -
which may also be the problem.

Unfortunately I can not help much... You can try different / new
versions of hibernate - maybe they fix the problem...


Best,


Raphael
