Description
|
I found this while testing. It occurs in Merlin as well as Hopper.
It only occurs when rlogged into jano (Solaris 2.6) and displaying
back to my machine (gradgrind - solaris 2.7) - not when I run it at
the console on gradgrind.
The problem occurs on the Composite tab. It may be attempting to
transfer to the next tab (Font) when the exception is thrown.
Here is my output:
xxxxx@xxxxx :/home/echawkes( 41 )% setenv DISPLAY gradgrind:0.0

This seems to be a fonts problem.
The demo that throws the exception is java2d.demos.Fonts.AttributedStr .
The exception is thrown only when the application is run remotely, even
with the pixmaps support disabled:
[ xxxxx@xxxxx :] -< demo/jfc/Java2D >
#>../../../bin/java -Dsun.java2d.pmoffscreen=false -cp Java2Demo.jar

at sun.java2d.pipe.DuctusShapeRenderer.renderPath(DuctusShapeRenderer.java:57)
at sun.java2d.pipe.DuctusShapeRenderer.fill(DuctusShapeRenderer.java:49)
...
Also, I can't reproduce it on local display with the pixmaps turned
on and dga/shared memory turned off (to simulate the remote display
situation).
So the problem is probably in the way we use fonts when running remotely.
Reassigning to fonts engineer.
xxxxx@xxxxx 2002-03-11
========================================
I think we are passing out of bounds values because TextLayout is
misbehaving. Its happening when remote displaying but I don't know why
yet. The following simple program
import java.awt.*;
import java.awt.font.*;
public class BB {
public static void main(String args[]) {
FontRenderContext frc = new FontRenderContext(null, false, false);
Font font = new Font("dialog", Font.PLAIN, 12);
TextLayout tl = new TextLayout("str", font, frc);
//System.out.println(tl.toString());
System.err.println("bhgt="+ tl.getBounds().getHeight());
System.err.println("asc="+ tl.getAscent());
System.err.println("dsc="+ tl.getDescent());
System.err.println("ldg="+ tl.getLeading());
}
}
prints this displaying remotely :-
bhgt=-3.4028234663852886E38
asc=12.0
dsc=4.0
ldg=1.0
but a sensible value when displaying locally, or with the headless toolkit.
xxxxx@xxxxx 2002-03-11
============================
This can be reproduced in varying ways all the way back to JDk 1.2.
xxxxx@xxxxx 2002-04-17
================================
We have seen a new manifestation of this which I have tracked down.
When a strike is created it is created through a cache, The constructor
(hsGGlyphStrike::hsGGlyphStrike) first ask the scaler to count
the number of glyphs in the font and if that is > 0 it initialises the
metrics. The flaw is that if font initialisation failed for some reason
(and fGlyphCount is 0) then the metrics are never initialised. Subsequent
client queries then retrieve random uninitialised values.
I believe this is the underlying cause of all of these problems.
They are typically seen remotely because that is when we tend to run
into problems where fonts that are expected to be found aren't found.
For many fonts it isn't a problem because we can fall back to using T2K
rather than the Xserver (if we were using the Xserver at all).
But for fonts which were not located as files then there is no fall back
and we hit this bug.
In this case a problem arose displaying from Solaris to Linux because the
font properties now explicitly mapped F3 fonts that previously would have
just "not found". a "default" font would have been substituted. Its probably
worth noting that not finding these fonts means that historically almost all
remote displays from Solaris to any system *other* than Solaris would trigger
a "loadfonts()"
[[ASIDE: The loadfonts is triggered because null is returned by a call in
initTerminalNames() to getFileNameFromPlatformName(). Fixing that
requires reworking some code structure so that it would not do the loadfonts
where it was not going to help. ie it will not help if it was a native font
and the display is remote. It may still help if its a remote display and
the font is file-based. So you can only avoid loadfonts when you know that
it is a native-only font and that you will not be able to set the X font path
to locate any more fonts than are already located]].
The simple fix is to initialise the metrics to 0 values. This then
treats these fonts as having no glyphs and "zero" metrics. A more complete
fix is to discard the useless composite slot or to replace it with a
targetted substitute.
Substituting the default font (dialog) as was currently happening is
questionable since dialog uses the components that weren't found.
We should also examine if the new code fixed under 4321790 should try to
handle this. It could try to determine if a native font that is "mapped"
by explicit font properties entries is actually available via native APIs
and subsitute a default if it isn't.

I am able to reproduce the very same behaviour locally on
Windows NT but cannot provide an easy test case.

This seems to be duplicate of 4485298 which is open since
Jul 27, 2001!

Digging even further I discovered that this is a known bug
(4190780) since Nov 17, 1998.

I am seeing the the same PRException: endPath: badPath
exception under Windows NT as well under 1.4.0_02. It is not
reliably reproducible but results in the JVM crashing and the
following appears in the Dr. Watson log:
