DO NOT REPLY [Bug 47917] New: Text rendering broken in MacOS X 10.5

https://issues.apache.org/bugzilla/show_bug.cgi?id=47917

           Summary: Text rendering broken in MacOS X 10.5
           Product: Batik
           Version: 1.8
          Platform: PC
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: major
          Priority: P3
         Component: GVT Text
        AssignedTo: batik-dev@xmlgraphics.apache.org
        ReportedBy: helder.magalhaes@gmail.com


There have been several (somehow recent) reports in the mailing list [1] [2]
[3] regarding a MacOS-specific issue with text rendering, namely what seems to
be a regression in version 10.5. Reports also aim towards a workaround
consisting in disabling Quartz, so I'm documenting this in order to try
gathering more information on this issue and/or to server as a placeholder for
patches.

This may also help fixing/working around the issue reported in issue 41451.

Note that I've set the OS as Mac OS X 10.4, although this seems to be specific
to version 10.5 (which is not available in the list). Confirmations on which
specific MacOSX version do the symptoms reproduce are welcome!

According to the reports, a possible fix would be detecting [1] [2] the
specific platform and tweaking the settings in accordance. Something like:

if(System.getProperty("os.version").equals("10.5")){
  System.setProperty("apple.awt.graphics.UseQuartz", "false");
}

There is a couple of pending issues with the above code:
1. There isn't enough evidence that this is really MacOS X 10.5 specific, more
feedback is welcome (as stated in comment 0);
2. I don't much of an idea on where to place this sort of code. Placing
anywhere within the GVT text classes should help, but I invite anyone with
better Java skills to make a more specific proposal and/or submit a patch.

Problem is occuring for me on OS X Mountain Lion (10.8.1).

Previously it was not occuring, e.g. on Snow Leopard.

I guess this should block the 1.8 release. There are apparently a couple ways
to workaround this and I'd really welcome some help (see comment 1) in order to
try to disentangle this.
