@joransiu fyi. Not sure if this is zLinux specific or something recently changed in this area.
CharacterDataLatin1
int getProperties(int ch) {
char offset = (char)ch;
int props = A[offset]; <- line 72
return props;
}
static final int A[] = new int[256];
To get there it went through CharacterData.of() and presumably ch >>> 8 == 0 was true.
static final CharacterData of(int ch) {
if (ch >>> 8 == 0) { // fast-path
return CharacterDataLatin1.instance;
} else {
switch(ch >>> 16) { //plane 00-16
case(0):
return CharacterData00.instance;
case(1):
return CharacterData01.instance;
case(2):
return CharacterData02.instance;
case(14):
return CharacterData0E.instance;
case(15): // Private Use
case(16): // Private Use
return CharacterDataPrivateUse.instance;
default:
return CharacterDataUndefined.instance;
}
}
