Zusammenfassung

0000029: barista is unable to load java.lang.Throwable and java.awt.Container

Beschreibung

The decoding of the ClassFile into ClassDefinition fails because some bytecodes are not recognized, when using array types in the constant pool where barista expects only class_or_interface.

I've patched barista for this problem (see email for a darcs generated patch).

Zusätzliche Information

Applying the small program:
open BaristaLibrary

let _ =
    let cf = ClassFile.read (InputStream.make_of_channel (open_in Sys.argv.(1))) in
    let cd = ClassDefinition.decode cf in
    let cf' = ClassDefinition.encode cd in
    ClassFile.write cf' (OutputStream.make_of_channel (open_out Sys.argv.(2)))

to the whole classpath standard library reveals some other issues when comparing input and output files. I didn't investigate anything else yet.

Notiz
(0000173) xclerc (Administrator) 2009-03-22 16:25	This is indeed a very unfortunate bug; the "LDC", "LDC_W", and "INVOKEVIRTUAL" instructions can take an array type as their (first) parameter. This as been fixed for the various parts of Barista: API (both OCaml and Java), assembler, and disassembler. As a result, all the classes of the JDK 1.6 can be loaded by Barista.
