Summary: ArrayIndexOutOfBoundsException in ArabicTextHandler with
Arabic diacritics
Key: BATIK-1074
URL: https://issues.apache.org/jira/browse/BATIK-1074
Project: Batik
Issue Type: Bug
Affects Versions: 1.7
Reporter: Robert Gurol
Priority: Minor
Trying out some Arabic characters, I got a ArrayIndexOutOfBoundsException in
ArabicTextHandler when the text contained Arabic diacritics
Here's a fix that works for my input:
ArabicTextHandler.doubleCharRemappings is missing some array entries:
<pre>
...
null, // 0x0629
// those were missing!
null, // 0x062A
null, // 0x062B
null, // 0x062C
null, // 0x062D
null, // 0x062E
null, // 0x062F
null, // 0x0630
...
</pre>
