unsigned values values should be stuffed into Java signed values like Java does

Key: JRUBY-4056
URL: http://jira.codehaus.org/browse/JRUBY-4056
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.4.0RC1
Reporter: Thomas E Enebo
Fix For: JRuby 1.4
This is idomatic code. I use this in image_voodoo more or less:
{noformat}
byte reverse[] = new byte[256];
for (int j=0; j<200; j++){
reverse[j]=(byte)(256-j);
}
ByteLookupTable blut=new ByteLookupTable(0, reverse);
{noformat}
In image_voodoo it looks like:
{noformat}
NEGATIVE_OP = LookupOp.new(ByteLookupTable.new(0,
(0...254).to_a.reverse.to_java(:byte)), nil)
{noformat}
However this breaks in 1.4.0RC1
