There seems to be a bug in 'javac', which lets you implicitly typecast a char
to a byte. Eg:
public class Test {
public static void main(String args[]) {
byte b = 'a';
}
'javac Test.java' compiles fine. That's from the Blackdown 1.3.0 JDK.
'jikes Test.java' reports:
Found 1 semantic error compiling "Test.java":
3. byte b = 'a';
<->
*** Error: A byte value must be an integer value (note that a character literal is not
an integer value) in the range -128..127.
Which makes perfect sense, since a char is 16 bits, and a byte is 8 bits. This
is relevant to httpclient, which would not compile with jikes:
[javac] Found 22 semantic errors compiling
"/home/jeff/apache/jakarta/jakarta-commons/httpclient/src/java/org/apache/commons/httpclient/URIUtil.java":
[javac]
[javac] 703. case '0':
[javac] <->
....
I fixed httpclient with a typecast (email waiting in a moderator's queue
presumably), but I thought I'd raise awareness of the issue here, and take the
opportunity to do a bit of jikes advocacy ;)
