Where is no changes in ScriptRuntime.getInterpreterFromCompositeId() so
you could use it as before.

Yes this is correct, but this will give you interpreters for all
environment's.

For getting default interpreters for local environment please use
following snippet:
String nature = ...
String environmentId = LocalEnvironment.ENVIRONMENT_ID;
ScriptRuntime.getDefaultInterpreterInstall(new
DefaultInterpreterEntry(nature, environmentId));


Also Jae:
Do you have you DLTK based Perl implementation source in public access?
If it is I've could check it out and send you patches if we made some
broke changes.

Best regards, Andrei Sobolev.
