[ExM Users] stc unsupported class error

[Tim Armstrong]

I haven't seen that one before.  It sounds like it's being run with an
older version of Java than it was compiled with.

Java class version 51.0 corresponds to java 7 (
http://en.wikipedia.org/wiki/Java_class_file#General_layout), so it seems
like it must be getting run with an older version.

You could try the -V switch to STC to see which java it's being run with,
and then -j /path/to/jvm/bin/java to force a different java version.
