Hi!
This is because Java has a maximum method length of 64 KB. For Flink <=
1.13 please set table.generated-code.max-length to less than 65536 (~8192
is preferred) to limit the length of each generated method.
If this doesn't help, we've (hopefully) completely fixed this issue in
Flink 1.14 by creating a brand-new module called the java-code-splitter.
For now you might want to make the length of your SQL shorter and wait for
the release of Flink 1.14.
