Product Name: Spectrum Technology Platform™
Product Feature: Installation / Upgrade

 

Issue

After applying patch S11 to Spectrum, the service fails to start and the following errors are encountered in the server log.
 
ERROR [Main] Failed to start bean 'enterpriseServer'; nested exception is java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'indexService' defined in URL [jar:file:/C:/Program%20Files/Pitney%20Bowes/Spectrum/server/lib/spectrum-server-index-elasticsearch-external-19.1.jar!/spring/spectrum-container-index-elasticsearch.xml]: Invocation of init method failed; nested exception is java.lang.RuntimeException: java.net.MalformedURLException: For input string: "9200:9200"
org.springframework.context.ApplicationContextException: Failed to start bean 'enterpriseServer'; nested exception is java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'indexService' defined in URL [jar:file:/C:/Program%20Files/Pitney%20Bowes/Spectrum/server/lib/spectrum-server-index-elasticsearch-external-19.1.jar!/spring/spectrum-container-index-elasticsearch.xml]: Invocation of init method failed; nested exception is java.lang.RuntimeException: java.net.MalformedURLException: For input string: "9200:9200"

In the server log there are multiple references to "9200:9200"
 
Caused by: java.lang.RuntimeException: java.net.MalformedURLException: For input string: "9200:9200"

 

Cause

This is caused by an incorrect entry in the 'spectrum-container.properties' file under the “spectrum.index.addresses” property. In a 2019.1 Spectrum environment which was upgraded from 2018.2, the following entry exists:
 
spectrum.index.addresses=localhost:9200

 

Resolution

UPDATED: June 11, 2020
Remove the port 9200 entry from the spectrum.index.addresses property in the spectrum-container.properties file located under C:\Program Files\Pitney Bowes\Spectrum\server\conf so that it looks like the valid values shown below:
 
spectrum.index.addresses=localhost
