Workaround: You can manually update two files where the Spectrum OneClick saves the changes.

• $SPECROOT/custom/common/config/tomcat-server-config.xml    (this file is only used in Spectrum upgrade, to preserve the current memory configuration)
• $SPECROOT/tomcat/bin/catalina.sh    (file used to start the Spectrum Tomcat service)

And restart the Spectrum Tomcat service ($SPECROOT/tomcat/bin/stopTomcat.sh / startTomcat.sh)
