Comment (by mevenson):

 Current thinking on resolution of issue:

 1.  Un-deprecate SYS:RUN-SHELL-COMMAND.  Use the pre Java 7 APIs as best
 we can to support invoking programs.

 2.  Re-code the SYS:RUN-PROGRAM Java callsite linkages so that ABCL may be
 compiled on pre-Java7 JDKs.  Produce an intelligible error if it is
 invoked on a pre-Java7 JVM.

 3.  Create an API to determine runtime JVM version. Wrap UIOP/RUN-PROGRAM
 invocation in some sort of handler that will "fall back" to using SYS:RUN-
 SHELL-COMMAND if it has compatible behavior via specified args.  This will
 potentially be fairly ugly code ASDF-side so we might provide a shim that
 UIOP/RUN-PROGRAM invokes that contains the logic outside the ASDF code
 base.
