    at java.lang.Object.wait(Native Method)
    at java.awt.MediaTracker.waitForID(MediaTracker.java:677)

    at javax.swing.ImageIcon.<init>(ImageIcon.java:217)



Steps to Reproduce

  1. Log in to the application > Designer Studio.
  2. Create a section and add an Image Icon control.
  3. Reference this image using an external image URL (Amazon S3 bucket URL).


Root Cause



Issue in Java Swing API when loading external images in which the Thread hangs when the external URL is unavailable or if the connection is slow.


Resolution

  1. Apply HFix-48358.
  2. Correct the Proxy configuration to use:

    -Dhttps.proxyHost=<proxy host name / ip>
    -Dhttps.proxyPort=port -Djava.net.useSystemProxies=true ..
This is performed because the AWS S3 Bucket uses SSL or HTTPS connection.
