Parser fails on "1E+5"

[GoogleCodeExporter]

* What steps will reproduce the problem?

Try executing either of these lines:
    Double x = new Gson().fromJson("1E+5", Double.class);
    BigDecimal y = new Gson().fromJson("1E+5", BigDecimal.class);

* What is the expected output? What do you see instead?

The expected result is a Double or BigDecimal containing the value 100000.
The actual behaviour is a NumberFormatException thrown from within the
java.math.BigDecimal constructor.  The key line is in the method
JsonParser.JsonNumber():

    n = new java.math.BigDecimal(intpart + fracpart + exppart);

At this point, fracpart is null because there is no decimal point in
"1E+5", and so the string addition produces "1nullE+5".  Is this a bug
in JsonParser.jj or perhaps even in the parser generator?

* What version of the product are you using? On what operating system?

I'm using Gson release 1.2.3 on Linux.
