java-1.8.0-openjdk-devel: Should have lower priority in alternatives
Last modified: 2013-07-18 01:56:20 EDT
Description of problem:
JDK 8 is still in development and it currently doesn't work at all (see bug # and bug #964406 and bug # 964408). Even if these bugs are fixed new ones may appear as Java 8 is still in development.
In my opinion java-1.8.0-openjdk should have lower priority in alternatives that java-1.7.0-openjdk so that if user installs both java and java8 java takes precedence. Otherwise installing java8 will break all Fedora applications and it will be selected as system default Java implementation.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
update-alternatives --display java
/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java - priority 170019
/usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java - priority 180000
jre-1.8.0-openjdk.x86_64 has lower priority than jre-1.7.0-openjdk.x86_64
I am not sure I agree.
Please note that java-1.8.0-openjdk will not get pulled in as a dependency of another package. All Java packages should (unless I made a mistake) depend on java-1.7.0-openjdk. The only way to have java-1.8.0-openjdk end up on your system is if you install it explicitly yourself. If that's the case, I think it sounds sensible (not desirable, I admit) to expect you to switch alternatives yourself if you notice it has bugs.
What do you think a suitable priority might be?

Considering the experimental status of java-1.8.0-openjdk I don't think it should be default system Java. I expect people would install JDK 8 to try it out, not to use it as default JVM for running all Java applications in the system. Default in alternatives should be JDK which is best suited for the system, not necessarly the highest version. In my opinion until JDK 8 is ready for production JDK 7 should remain default (i.e. have highest priority in alternatives).

Anything lower than 170019. Perhaps 0.
