[jira] Commented: (HARMONY-2128) DaCapo chart requires DISPLAY environment to be set

["Dmitriy Matveev (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-2128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12472628 ] 

Dmitriy Matveev commented on HARMONY-2128:
------------------------------------------

To fix this issue we need to implement Headless mode [1].
AWT font rendering is dependent on X server so we will split this task on 2 subtasks: Headless mode implementation without font rendering and font rendering for headless mode.

>          Issue Type: Bug
>          Components: App-Oriented Bug Reports
>         Environment: Linux, DaCapo benchmarks 2006-10 (from www.dacapobench.org)
>            Reporter: Robin Garner
>            Priority: Minor

> The DaCapo benchmark runs successfully if DISPLAY is set, but fails if it is not.  It shares this issue with classpath-based VMs (jamvm, jikesrvm), but not with production vms (IBM J9 and Tokyo JIT, Blackdown 1.4.2, SUn jdk 1.5.0 and 1.6.0, and jrockit).  
> Some component of AWT is being initialised too early would be my guess.
> To reproduce the problem:
> - download dacapo-2006-10.jar from sourceforge
> - java -jar dacapo-2006-10 chart
> with DISPLAY set it works, without it doesn't.
