> When running Pack200 on the attached testcase, I get a:
> Thread [main] (Suspended (exception Pack200Exception("Cannot have a negative range")))
> SegmentConstantPool.getValue(int, long) line: 65
> AttributeLayout.getValue(String, long, SegmentConstantPool) line: 76
> AttributeLayout.getValue(long, String, SegmentConstantPool) line: 198

> Segment.unpack(InputStream, JarOutputStream) line: 352
> Archive.unpack() line: 146
> TestUnpack.main(String[]) line: 15
> This appears to be due to the fact that value is -116 at the following point in AttributeLayout.getValue():
