bootstrapping icedtea with gcj 4.3

[Bernhard Rosenkraenzer]

Hi,
I've just tried to bootstrap icedtea (current hg) with gcj 4.3 from SVN (the 
first semi-official gcc with generics support).

It compiles a lot of files, but finally barfs with

    [javac] Compiling 2 source files 
to /usr/src/ark/BUILD/icedtea/openjdk/control/build/linux-i586/langtools/build/toolclasses                                     
[javac] ----------
    [javac] 1. ERROR 
in /usr/src/ark/BUILD/icedtea/openjdk/langtools/make/tools/CompileProperties/CompileProperties.java 
(at line 220)
    [javac]     List<String> sortedKeys = new ArrayList<String>();
    [javac]     ^^^^
    [javac] The type List is not generic; it cannot be parameterized with 
arguments <String>
    [javac] ----------
    [javac] 2. ERROR

    [javac] ies.java (at line 220)
    [javac]     List<String> sortedKeys = new ArrayList<String>();
    [javac]          ^^^^^^
    [javac] Syntax error, parameterized types are only available if source 
level is 5.0
[...]


Are there any known workarounds for this, other than using the gcc 4.1 fork?

Regards,
