[Soot-list] "Operands in conditional operator does not match" using Soot eclipse plug-in

[Joe Siponen]

The project is a JDK5 one, but I tried the --polyglot switch and tried to run soot on the source files. This was the result:

Starting from Soot's class library:
soot.Main --d /Users/joes/Documents/signe_workspace/signe/sootOutput --cp [...] --process-dir --keep-line-number --polyglot --xml-attributes --src-prec java 
Soot started on Wed Dec 02 13:41:21 CET 2009
compilation failed: Could not compile

Other information that may (or may not be relevant) is:

OS: Mac OS X Snow Leopard

java version "1.5.0_20"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_20-b02-315)
Java HotSpot(TM) Client VM (build 1.5.0_20-141, mixed mode, sharing)
