Hi Tim,

I see a different exception:

org.h2.jdbc.JdbcSQLException: General error:
"java.lang.ArrayIndexOutOfBoundsException"; SQL statement:

This is here:

public long readVarLong() {
        long x = data[pos++];
        if (x >= 0) {
            return x;
        }
        x &= 0x7f;
        for (int s = 7;; s += 7) {
>            long b = data[pos++];
            x |= (b & 0x7f) << s;
            if (b >= 0) {
                return x;
            }
        }
    }

And I also don't see it with -Xint. I tested both 1.5 and 1.6 builds.
