   I'm not quite sure of the extent of "extensive", but yes, Java (not all   
   upper-case, please) was one of the many, many tools used on MER.

   There is Java code in the rover. So what?

   uh, the first MER lander is rebooting frequently, with (as far as I   
   understand these things) no reason to blame the Java Virtual Machine.   
      
   Java code does not have to be "bloated, buggy code". Virtual machine   
   architectures are a classic way to to create a small, tight program --   
   consult Knuth for details.   
      
   "Bloated, buggy code" is more common in non-Java environments, e.g., MS   
   Office running on MS Windows.   
      
      
   > Somehow, I'm afraid rover "bluescreened"   
      
   "Bluescreen" is a Microsoft-ism. Note that Microsoft is legally   
   restrained from doing much of anything with Java.
