Hello,
The bughttps://bugs.openjdk.java.net/browse/JDK-8019201 is fixed. And
effectively, if I run the test includes in the
commithttp://hg.openjdk.java.net/jdk8/2d/jdk/rev/833f05116f7b :
* It is OK with 1.7.0_21-b11.
* It is KO with 1.7.0_25-b15.
* It is OK with 1.7.0_40-b43.
However, I have always similar problem with JDK 1.7.0_40-b43 and the
AffineTransformOp JDK class.
I do not know enough about the Batik library and even less ConvolveOp
and AffineTransformOp JDK classes to adapt the test to reveal the
problem with AffineTransformOp.
Does someone who knows enough these classes could adapt the test?
Best regards,
Laurent
Hi everyone,
the latest security update of Oracle's JDK/JRE 1.7.0_25 breaks many if
not all BufferedImageOp.filter implementations.
BATIK 1.7 uses these operations in several places
sources/org/apache/batik/ext/awt/g2d/AbstractGraphics2D.java
sources/org/apache/batik/ext/awt/image/renderable/ConvolveMatrixRable8Bit.java
sources/org/apache/batik/ext/awt/image/renderable/MorphologyRable8Bit.java
sources/org/apache/batik/ext/awt/image/rendered/AffineRed.java
sources/org/apache/batik/ext/awt/image/rendered/Any2LsRGBRed.java
sources/org/apache/batik/ext/awt/image/rendered/Any2LumRed.java
sources/org/apache/batik/ext/awt/image/rendered/Any2sRGBRed.java
sources/org/apache/batik/ext/awt/image/rendered/ProfileRed.java
sources/org/apache/batik/svggen/SVGGraphics2D.java
and consequently BATIK may break down with unexpected
"java.awt.image.ImagingOpException: Unable to transform src image"
exceptions.
The only workaround I have been able to find so far is patching BATIK
sources to no longer call BufferedImageOp.filter directly on the source
and destination image, but to filter two ARGB BufferedImage copies.
A corresponding bug report
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8019201 has been
filed with Oracle. However, the report does not mention the full extend
of this problem - since filing the report, I have found Linux JDKs and
additional BufferedImageOp implementations such as AffineTransformOp
suffering from this problem, too.
A project of mine has had two reports of this very probelm from users
using 1.7.0_25 on Windows, and I can reliably reproduce it myself with
OpenJDK 1.7.0_25 on Linux.
Is there any way we can poke Oracle to fix the regression faster?
