> Currently, DRLVM supports "compressed" strings (where character occupies 1 byte instead of 2). This improves performance on operations with pure ASCII strings (like ones present in XML processing).
> But this implementation depends on the presence of special field 'bvalue' of type 'byte[]' in java/lang/String and the support for operations on "compressed strings" in this class. It would be nice to have this support implemented in java.lang.String. It will work only with VMs supporting "compressed" one-byte strings.
