In normal Lua, the interpreter will evaluate an expression:

$ lua
> 1 + 1
2

In LuaJ, evaluating a bare expression like 1 + 1 results in a LuaError with this message: unexpected symbol 287 (ğ). This happens whether I'm loading the expression using the Java API or I'm running LuaJ as an interactive REPL.

This is clearly a bug, as there's no such character in the input.

In LexState.java, 287 is the integer code for TK_NUMBER. This error seems to indicate that the compiler is looking for more input, and is (by default at least) expecting to see a number. The error is thrown in LexState.java in the primaryexp() method.

The script mytab = { results in a similar error, with unexpected symbol 286. Symbol 286 is TK_EOS, meaning end of string.
