---------------------------------------------
I tried to change both table-runtime and table-planner-loader at {{compile}}
scope, and I get this different exception:
{code:java}

I investigated this one and I have some findings:
* Looking in the built jar of flink-table-runtime, the class is there. So
there's no issue with the packaging itself.
* Executing {{mvn exec:java
-Dexec.mainClass="org.apache.flink.table.examples.java.basics.StreamSQLExample"
-pl flink-examples/flink-examples-table}} works fine, so both code and maven
configuration are correct
* Debugging the code, the correct classloader (the AppClassLoader built from
IDEA) is used for resolving this class.
So my feeling is that there's something wrong with IDEA here.
