Eclipse warns about using a 1.4 JRE
Last modified: 2009-01-09 00:14:20 EST
Description of problem: Eclipse on Fedora 8 seems to have some weird ideas about JREs. If I open configuration - Java - Compiler, there's a warning at the top about "Classfile compatibility must be greater or equal than source compatibility" (all of the compliance levels are at 6.0 by default). If I change them all manually to 6.0, then the warning goes away. Also, when I create a Java project, there's a warning at the bottom of the creation wizard that says: "The current workspace uses a 1.4 JRE with compiler compliance level 1.7. This is not recommended and either the JRE or the compiler compliance level should be changed." There's also a link to configure the compliance level which takes me back to the earlier compiler configuration page, which still has 6.0 as all of the compliance levels. None of this seems to cause any difficulty in practice. Perhaps Eclipse isn't expecting a 1.7 compiler? Version-Release number of selected component (if applicable): eclipse-jdt-3.3.0-30.fc8 How reproducible: Every time Steps to Reproduce: 1. Open Eclipse on a clean workspace
Yeah, Eclipse isn't really ready for 1.7 VMs yet. It seems to work well enough for me, though. You say that this doesn't seem to cause any difficulty in practice and I haven't seen any difficulties either. Should we keep this open?
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
