[Bug libgcj/28979] New: GCJ errors out when compiling .class files produced by Scala 2.1.8

[vnasardinov at gmail dot com]

I'm getting an error when trying to compile the following classes with
gcj:

 | $ scalac hamming.scala 
 | $ ls -lh *.class
 | -rw-rw-r-- 1 vadim vadim 1.1K Sep  7 20:16 hamming$$anonfun$0.class
 | -rw-rw-r-- 1 vadim vadim 1.1K Sep  7 20:16 hamming$$anonfun$1.class
 | -rw-rw-r-- 1 vadim vadim 1.1K Sep  7 20:16 hamming$$anonfun$2.class
 | -rw-rw-r-- 1 vadim vadim 1.5K Sep  7 20:16
hamming$$anonfun$3$$anonfun$4.class
 | -rw-rw-r-- 1 vadim vadim 1.5K Sep  7 20:16
hamming$$anonfun$3$$anonfun$5.class
 | -rw-rw-r-- 1 vadim vadim 1.5K Sep  7 20:16
hamming$$anonfun$3$$anonfun$6.class
 | -rw-rw-r-- 1 vadim vadim 1.3K Sep  7 20:16 hamming$$anonfun$3.class
 | -rw-rw-r-- 1 vadim vadim  868 Sep  7 20:16 hamming.class
 | -rw-rw-r-- 1 vadim vadim 2.4K Sep  7 20:16 hamming$.class
 | $ jar cf hamming.jar *.class
 | $ gcj --main=hamming
--classpath=/usr/local/scala/share/scala/lib/scala-library.jar hamming.jar 
 | hamming.scala: In class 'hamming$':
 | hamming.scala: In constructor '()':
 | hamming$.java:0: warning: assignment to final static field `MODULE$' not in
class initializer
 | /tmp/cc8cPsFr.s: Assembler messages:

The .class files were produced by Scala 2.1.8:
  http://scala.epfl.ch/downloads/distrib/files/scala-2.1.8.tar.gz

The above is under the following version of GCJ:

 | $ gcj -v
 | Using built-in specs.
 | Reading specs from /usr/lib/gcc/x86_64-redhat-linux/4.1.1/libgcj.spec
 | rename spec lib to liborig
 | Target: x86_64-redhat-linux
 | Configured with: ../configure --prefix=/usr --mandir=/usr/share/man \
 |   --infodir=/usr/share/info --enable-shared --enable-threads=posix \
 |   --enable-checking=release --with-system-zlib --enable-__cxa_atexit \
 |   --disable-libunwind-exceptions --enable-libgcj-multifile \
 |   --enable-languages=c,c++,objc,obj-c++,java,fortran,ada \
 |   --enable-java-awt=gtk --disable-dssi \
 |   --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre \
 |   --with-cpu=generic --host=x86_64-redhat-linux
 | Thread model: posix
 | gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)

I will attach the offending .jar file in a minute.
