Subject Re: Index on SYSTEM.LOG failed
Date Fri, 25 Oct 2019 15:05:51 GMT
My question was not meant to imply that creating any index should fail 
in the same manner as what you see here.

https://docs.oracle.com/javase/8/docs/api/java/lang/IllegalAccessError.html

An IllegalAccessError means that the PQS tried to access this class but 
it failed (for some reason). Of course, the thin client is not going to 
be trying to access code that it can't.

It could be that there is an issue in creating a local index against the 
system.log table, but this real error is being lost because of your 
classpath issue. Can't really say anything definitively with the 
information you've provided.
