How did you produce the problem that is reported in the JIRA? I know that
this code alone does not throw this exception at the codegen.
```
case class Foo(`1_something`: String)
val test = Seq(Foo("HelloWorld!")).toDS()
```
```
java.lang.RuntimeException: Error while encoding:
java.util.concurrent.ExecutionException:
org.codehaus.commons.compiler.CompileException: File 'generated.java', Line
316, Column 15: failed to compile:
