NullPointerException in org.apache.pdfbox.pdmodel.graphics.PDShading.toString,
when getDomain() returns null
------------------------------------------------------------------------------------------------------------
Key: PDFBOX-1013
URL: https://issues.apache.org/jira/browse/PDFBOX-1013
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 1.5.0
Environment: Windows 7, and Ubuntu 8.04
PDFBox 1.5.0
Reporter: Craig Stires
Priority: Minor
Fix For: 1.6.0
The problem is that the toString method is called on objects which may have
been returned as null
The suggested fix to this, in the attached patch is to check if null, then
write an empty string
String s = "Shading " + shadingname + "\n"
+ "\tShadingType: " + getShadingType() + "\n"
+ "\tColorSpace: " + sColorSpace + "\n"
+ "\tAntiAlias: " + getAntiAlias() + "\n"
+ "\tCoords: " + (getCoords() != null ? getCoords().toString() :
"") + "\n"
+ "\tDomain: " + (getDomain() != null ? getDomain().toString() :
"") + "\n"
+ "\tFunction: " + sFunction + "\n"
+ "\tExtend: " + (getExtend() != null ? getExtend().toString() :
"") + "\n"
+ "\tRaw Value:\n" +
