Sdoutl.jar WKT bug

Question

Hi, using the WKT class, we ran into the following issue where if you call WKT.toJGeometry() it chokes on scientific notation like this: POLYGON ((-8.2907617E8 4.2403891E8, -8.2907617E8 4.2403891E8, -8.2907617E8 4.2403891E8, -8.2907617E8 4.2403891E8, -8.2907617E8 4.2403891E8))
<p>
As you can see, the wkt string has scientific notation in it. This is slightly odd, since we created the wkt byte[] from the WKT class itself by using WKT.fromJGeometry()
<p>
This means the round-trip between WKT and JGeometry does not appear to work.
<p>
This is easily reproducible with the following code:
<p>
JGeometry jGeometry = new JGeometry(-829076170, 424038910, -829076170, 424038910, 8307);
WKT wkt = new WKT();
byte[] bytes = wkt.fromJGeometry(jGeometry);
for(byte b : bytes) { System.out.print((char)b); }
JGeometry roundTrip = wkt.toJGeometry(bytes);  // <- THROWS EXCEPTION<p>
The stack trace is:
<p>
java.lang.RuntimeException: -3

Answer 1

While this still seems to be a bug in the WKT class, the coordinates we were using were in an int format, and we were not properly transposing them to degrees. They needed a division by 10^7, so when we do that, this problem goes away for us...however, even if the coordinates as listed are not seemingly valid earth coordinates for SRID 8307, it still seems like the WKT parser should be able to properly handle java's toString on Doubles with scientific notation.
