double values cannot be read from dmr response ---------------------------------------------- Key: AS7-4126 URL: https://issues.jboss.org/browse/AS7-4126 Project: Application Server 7 Issue Type: Bug Components: Console Affects Versions: 7.1.0.Final Reporter: Rob Cernich Assignee: Heiko Braun Fix For: 7.1.2.Final (EAP) This appears to be a bug in the GWT compiler. The compiler turns the following: {code:java|title=DataInput.readDouble()} return IEEE754.toDouble(bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++]); {code} into: (effectively; the GWT compiler is adding a set of parentheses around the parameters passed to the native function) {code:java|title=DataInput.readDouble() compiled} return IEEE754.toDouble(new byte[] {bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++], bytes[pos++]}); {code} This results in all double values in the model being interpreted as NaN. I've patched the code I'm using in SwitchYard as follows: {code:java|title=DataInput.java} public double readDouble() throws IOException { byte doubleBytes[] = new byte[8]; readFully(doubleBytes); return IEEE754.toDouble(doubleBytes); } {code} {code:java|title=IEEE754.java} public static native double toDouble(byte[] bytes) /*-{ var ebits = 11; var fbits = 52; // Bytes to bits var bits = []; //snip... } {code}
