I believe this issue relates to the partial class loader implementation in the current Apache Harmony classes in libraryInterface.

bloat really tries to load java.lang.Object from classpath, but classpath differ:

Sun's JDK 1.6: Loading class 'java/lang/Object' from
/home/shade/trunks/bloat/bin:
/opt/sun-jdk-1.6.0.07/jre/lib/resources.jar:
/opt/sun-jdk-1.6.0.07/jre/lib/rt.jar:
/opt/sun-jdk-1.6.0.07/jre/lib/sunrsasign.jar:
/opt/sun-jdk-1.6.0.07/jre/lib/jsse.jar:
/opt/sun-jdk-1.6.0.07/jre/lib/jce.jar:
/opt/sun-jdk-1.6.0.07/jre/lib/charsets.jar:
/opt/sun-jdk-1.6.0.07/jre/classes:null

RVM+Harmony: Loading class 'java/lang/Object' from
/home/shade/trunks/bloat/bin:null:null

Hence I suspect bloat looks up for bootclasspath via System.getProperty("sun.boot.class.path") which is not set.

rvm-harmony-bootclasspath-v1.patch
Sets the missed system property.

Fixes Dacapo:bloat failure on JikesRVM r14973, Harmony classlib r694933 + build fix, Gentoo x86.
I'll bet it would fix another related issues too (like Soot one).
