Indeed this issue exists if JAVA_HOME refers to Harmony JRE:
echo $JAVA_HOME
.../classlib/trunk/deploy/jdk/jre
echo $LD_LIBRARY_PATH
.../classlib/trunk/deploy/jdk/jre/bin
echo $CLASSPATH=.../classlib/trunk/depends/jars/ecj_3.2/ecj_3.2.jar
ant -Dbuild.compiler=org.eclipse.jdt.core.JDTCompilerAdapter
...
[javac] 3608. ERROR in
/nfs/ins/proj/drl/coreapi/vgorr/GIT/classlib/trunk/modules/text/src/main/java/java/text/DecimalFormat.java
[javac] (at line 23)
[javac] import java.math.BigDecimal;
...
It means our build system doesn't work correspondingly for the self-hosting
mode.
Besides I'd like to note a lot of warning are generated when we use ECJ3.2.
Thanks,
Vladimir.

Are you sure ant is running with harmony's jvm and classlibs when
JAVA_HOME
is set to sun's path?
I am wanting to use the harmony classlibs and jvm with ant and the ecj
compiler. Hopefully this would make no dependencies on sun's java.
You know what. I didn't explicitly mention that I was trying to run this
with harmony. Whoops, sorry.
