Description Mikko Tiihonen CLA 2012-02-03 05:39:20 EST 
Build Identifier: I20120127-1145

All projects will start to complain errors like:

Build Path Problem: Unbound classpath container: 'JRE System Library [JavaSE-1.6]' in project xyx 


Furthermore in Preferences/Execution Environments it is not possible to explicitly mark jdk8 as compatible with any envirnoment because the Compatible JREs list is empty.



Reproducible: Always

Steps to Reproduce:
1. Install jdk8 from http://jdk8.java.net/download.html
I'm running: Java(TM) SE Runtime Environment (build 1.8.0-ea-b23)
2. Remove all other jdks from Preferences/Installed JREs
3. All projects fail to compile

We do not support jdk8 yet (and can not unless it is officially released). You can follow bug 358387 to check the progress on that.
Marking this as a dup for now.

At some point, perhaps well prior to resolution of bug 358387, we may have
to enable support for recognizing and allowing a user to deploy a JDK8 
runtime i.e we will not allow them to create a Java 8 project nor allow any
of the new constructs, but support use of JDK8 with a Java7 or Java6 project
say (with the usual warnings about not being a perfectly matched JRE)
Otherwise, we will impede anyone using eclipse from wanting to test JDK8.
Comment 3 Mikko Tiihonen CLA 2012-02-03 06:20:52 EST 
I just noticed I can import a jre execution environment description file.

Could someone point me to an example .ee file that describes standard oracle java7 jdk? Or better yet paste a working example of jdk8.ee here?

http://wiki.eclipse.org/index.php/Execution_Environment_Descriptions

This bug could then be marked as a known issue until initial jdk8 support arrives.
Comment 4 Dani Megert CLA 2012-02-06 03:06:06 EST 
We should be able to detect a JRE 8 and recognize it as non-fully compatible with < JREs < 8.
