On this recent thread, Joe Ess said that HashTable was the 2nd most frequently used class, after String.
Does anybody know why HashTable is used so frequently? Joe said it was used by the JVM for mapping purposes.

I've noticed HashTable showing up a lot in the profiler too even though we don't have ANY references to it in our code. Joe's explanation makes sense. Newer code would mostly use HashMap rather than HashTable. But the JVM was written before HashMap was invented.

Really by the JVM, or do you mean the Java API classes?

It wasn't me said it, it was Joe Ess, but yes, he said it was the JVM.
