has the same.

Environment

• Output Management Web Viewer 12.1
• Java
• Apache Tomcat®
  
  

Cause

Unprintable or Non-Numeric characters for a certain WVProfile.properties parameter value 

Resolution

From the log provided, it was determined that the WVProfile.properties file contained an invalid parameter setting - more to the point, a non-numeric where only a numeric is permitted.
Specifically, peruse line 10. Looking at it here, it appears to read:
000010 REPORTLIST.NumPerCacheDBQuery=50
Double check the WVProfile.properties file, even editing the file, over-typing the values, making sure there are no trailing spaces or other unprintable characters, saving the file and then recycling Apache Tomcat® and testing once again.
