> Hello,
> I have just noticed that the last C* version 2.1.3 reintroduced an old bug "CASSANDRA-8281".
> When closing the CQLSSTableWriter after adding rows it generated the following Exception:
> {code:title=Exception|borderStyle=solid}
> Exception in thread "main" java.lang.ExceptionInInitializerError

> Note that is this works correctly in 2.1.2 and not with 2.1.3, we can reproduce this
issue with the following code:
> {code:title=test.java|borderStyle=solid}
> import org.apache.cassandra.config.Config;
> import org.apache.cassandra.io.sstable.CQLSSTableWriter;
> public static void main(String[] args) {
>   Config.setClientMode(true);
>   // These folders needs must exist: mkdir -p /tmp/kspc/t1
>   CQLSSTableWriter w1 = CQLSSTableWriter.builder()
>     .inDirectory("/tmp/kspc/t1")
>     .forTable("CREATE TABLE kspc.t1 ( id  int, PRIMARY KEY (id));")
>     .using("INSERT INTO kspc.t1 (id) VALUES ( ? );")
>     .build();
>   try {
>     w1.addRow(1);
>     w1.close();
>   } catch (Exception e) {
>     System.out.println(e);
>   }
> }
> {code}
