Reverting back to 4.2.1.008 fixes this.

[Michael Offner]

This exception is happening while reading a file with help of a gzip inputstream but not inside Railo, this is happening while calling the Java code directly within a udf. are you a 100% sure downgrading solve the issue and this was not a coincidence?

Hi Micha. I am 100% certain. Consider the following code:

theString = "Railo is great!";
echo("Original String: " & theString & "<br>");

zippedFile = gzip(theString); // uses another UDF to gzip the string
echo("GZipped String: " & zippedFile & "<br>");

unzippedFile = ungzip(zippedFile);
echo("Unzipped String: " & unzippedFile);

function ungzip( String string='', String encode = 'base64' ){
    try {
        var bufferSize=8192;
        var byteArray = createObject("java","java.lang.reflect.Array").newInstance(createObject("java","java.lang.Byte").TYPE,bufferSize);
        var decompressOutputStream=createObject("java","java.io.ByteArrayOutputStream").init();
        var input=0;
        var decompressInputStream=0;
        var l=0;
        if(not isBinary(arguments.string) and arrayLen(arguments) is 1) return;
        if(arrayLen(arguments) gt 1){
            input=binaryDecode(arguments.string,arguments.encode);
        }else{
            input=arguments.string;
        }
        decompressInputStream=createObject("java","java.util.zip.GZIPInputStream").init(createObject("java","java.io.ByteArrayInputStream").init(input));
        l=decompressInputStream.read(byteArray,0,bufferSize);
       
        while (l gt -1){
            decompressOutputStream.write(byteArray,0,l);
            l=decompressInputStream.read(byteArray,0,bufferSize);
        }
        decompressInputStream.close();
        decompressOutputStream.close();
       
        return decompressOutputStream.toString();
    }
    catch (any e){
        writeDump(e);
    }
}

Run on 4.2.1.008 and you get:

Original String: Railo is great!
GZipped String: H4sIAAAAAAAAAAtKzMzJV8gsVkgvSk0sUQQA3bbHAQ8AAAA=
Unzipped String: Railo is great!

Run it on 4.2.2.002 and you get:

Original String: Railo is great!
GZipped String: H4sIAAAAAAAAAAtKzMzJV8gsVkgvSk0sUQQA3bbHAQ8AAAA=

Revert back to older version of Railo and works fine again.

We will check what is going on ...

FYI

the problem is the fix for this ticket

https://issues.jboss.org/browse/RAILO-3225

this has affected the function "binaryDecode" that is used within the UDF.

to decode a base64 string we have moved away from a apache library, because this library was not complaining about invalid inputs.

Problem is solved for next release

https://issues.jboss.org/browse/RAILO-3263

Thanks Micha - I saw 3225 and assumed it was the culprit, but my limited java skills prevented me from going much further in addressing it. I appreciate you looking into it.
