Description
ADDITIONAL SYSTEM INFORMATION :
Processor Intel(R) Xeon(R) CPU E5-2683 v4 @ 2.10GHz, 2095 Mhz, 2 Core(s), 2 Logical Processor(s)
System Type x64-based PC
OS Name Microsoft Windows 10 Enterprise
Version 10.0.15063 Build 15063
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)
A DESCRIPTION OF THE PROBLEM :
Rendering a Label using HTML text cause an NullPointerException when:
- The img attribute is empty e.g. "<html><img src=''/></html>"
- and the JComponent has a custom image base URL (BasicHTML.documentBaseKey)
REGRESSION : Last worked in version 8u221
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- Create a javax.swing.JLabel
- Set a custome BasicHTML.documentBaseKey URL for the JLabel using putClientProperty
- Set a HTML as text via setText("<html><img src=''/></html>")
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The configured ImageView.MISSING_IMAGE (html.missingImage) is rendered
ACTUAL -
A java.lang.NullPointerException is thrown see below:
