Issue/Introduction

After upgrading Spectrum to 20.2.x, the Spectrum WebTomcat process does not start properly. When looking at the <SPECROOT>/webtomcat/logs/catalina.out or stdout.log file, we see the following error:

Environment

Release : 20.2.x

Component : Spectrum OneClick

Resolution

This is due to an issue with the webswing.config file. The below steps will resolve this issue.

1. Stop the webtomcat process.

2. Open the <SPECROOT>/webtomcat/webswing/webswing.config file and change line 46 from:

"vmArgs" : "-Xmx1024m -Djavaws.cfg.jauthenticator=true -Dsun.awt.noerasebackground=true

to

"vmArgs" : "-Xmx1024m -Djavaws.cfg.jauthenticator=true -Dsun.awt.noerasebackground=true",

3. Save the file and then start the Webtomcat process.
