Summary: NegativeArraySizeException in
MultipleGradientContextPaint.calculateGradientFraction
s
Product: Batik
Version: 1.8
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: major
Priority: P2
Component: Utilities
AssignedTo: [email protected]
ReportedBy: [email protected]
Line 359 of org.apache.batik.ext.awt.MultipleGradientContextPaint compares the
float value of Imin to 0.0. However, due to float-point limitations, under some
conditions this value can be negative - leading to this exception stack trace:
java.lang.NegativeArraySizeException

The negative value is around 1e-07, and can be addressed by changing the
condition from (Imin == 0) to (Imin <= 0)
Thanks
