[Bug java/32967] New: [4.3 regression] gcjavac throws java exceptions on startup

["bero at arklinux dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I've installed gcc 4.2.1 and 4.3-svn in parallel, 4.2.1 as normal compiler, 4.3
with --program-suffix=-4.3 (and with contrib/download_ecj).

Trying to use gcjavac from 4.3 results in:

$ gcjavac-4.3 test.java
java.lang.NullPointerException
   at java.lang.String.<init>(libgcj.so.9)

Or, when forcing libgcj into the CLASSPATH:

$ CLASSPATH=/usr/share/java/libgcj-4.3.0.jar gcjavac-4.3 test.java

(test.java is just a simple hello world-style app)
