[IcedTea7] Bootstrap using GCJ-4.4 ?

[Damien Raude-Morvan]

Hi,

I'm trying to prepare some experimental OpenJDK-7 Debian packages based 
on Matthias Klose work. First step is to build current icedtea7 hg HEAD 
[0] but I haven't managed yet : I always get an exception during 
bootstrap (with GCJ) :

-create-import-jdk-stubs:
     [mkdir] Created dir: 
/tmp/buildd/openjdk-7-7b84/build/openjdk-boot/build/linux-amd64/langtools/build/genstubs
  [genstubs] Generating 81 stub files to 
/tmp/buildd/openjdk-7-7b84/build/openjdk-boot/build/linux-amd64/langtools/build/genstubs

BUILD FAILED
java.lang.NoClassDefFoundError: GenStubs
    at java.lang.Class.initializeClass(libgcj.so.10)
    at GenStubs$Ant.execute(Unknown Source)
[...]
Caused by: java.lang.ClassNotFoundException: 
javax.tools.JavaFileManager$Location
[...]
    at java.lang.Class.initializeClass(libgcj.so.10)
    ...15 more

You can get my full build log here : [1].

Some important informations :
- AFAIK, javax.tools.JavaFileManager$Location is only available since 
1.6 Java API level (so it's not bundled with GCJ classpath implementation).
- Bootstrap part end successfuly when using OpenJDK-6 as stage1 (getting 
other issues later on but that's another story...)
- IcedTea's Build server IcedTea fails with the same stacktrace [2].

Any ideas how to fix this ?
