Chae Lee created THRIFT-4003:
--------------------------------
Summary: Is there a reason why hexVal() in TJSONProtocol.java
throws exception when uppercase alphabet is given?
Key: THRIFT-4003
URL: https://issues.apache.org/jira/browse/THRIFT-4003
Project: Thrift
Issue Type: Question
Components: Java - Compiler, Java - Library
Reporter: Chae Lee
Priority: Trivial
Found out that passing unicode string "\uB300\uCE58" to Java server causes
"Expected hex character" in lib/java/src/protocol/TJSONProtocol.java:306.
{code:title=TJSONProtocol.java|borderStyle=solid}
// Convert a byte containing a hex char ('0'-'9' or 'a'-'f') into its
// corresponding hex value
private static final byte hexVal(byte ch) throws TException {
if ((ch >= '0') && (ch <= '9')) {
return (byte)((char)ch - '0');
}
else if ((ch >= 'a') && (ch <= 'f')) {
return (byte)((char)ch - 'a');
}
else {
throw new TProtocolException(TProtocolException.INVALID_DATA,
"Expected hex character");
}
}{code}
This is due to alphabet 'B' is not between '0' ~ '9' or 'a' ~ 'f'.
Not that it's causing major issues or anything, just curious if the if~ else
conditionals are set like this for a reason.
