Support have identified an issue where the OneClick console cannot be launched after upgrading to 9.4.3.
A tecdoc has already been written up / approved and is pending publication as a priority to advise on this, but to increase awareness and get this out among the Spectrum community below is the content of the pending tecdoc.
Error "HTTP Status 500 - Unable to compile class for JSP" error while connecting to OneClick server after upgrading to 9.4.3
A problem has been identified after upgrading to Spectrum 9.4.3 whereby you may see the above error when trying to launch the OneClick console.
The problem occurs as a result of old versions of tomcat jar files ecj*.jar being present in the $SPECROOT/tomcat/lib directory, which are not compatible with Java version 8 which ships with Spectrum 9.4.3.
The solution is a follows:
1. Stop Tomcat process.
2.Remove all old versions of ecj*.jar files located in the $SPECROOT/tomcat/lib directory leaving only the current version of this file:
3. Rename $SPECROOT/tomcat/work directory (it will be recreated on tomcat restart).
4. Start Tomcat.
You should now be able to launch the OneClick console.
this problem could arise on all supported platforms - and we saw this on Windows- and Linux-Servers. But also we see many successful upgrades to CA Spectrum R9.4.3.
Please ensure all CA Spectrum services (ahead of the SRAdmin) are truly stopped. Cheers, Joerg
