I built version 1.9.1 IcedTea, and then I modified a part of code at
icedtea6-1.9.1/openjdk-ecj/hotspot/src/share/vm/shark/sharkCompiler.cpp; I
tried to change to anther target that is supported in LLVM, I used this
instruction "builder.setMArch(x86);" instead of "builder.setMCPU(MCPU);". After
I rebuilt the program and executed it, I got a segmentation fault and generated
a bug report when process was terminated, I knew that the result was In
expectation. But when I redo to use original instruction and recompiled it, the
error message is still there, as following:


/home/shchiu/project/icedtea6-1.9.1/bootstrap/jdk1.6.0/bin/javap
javax.xml.transform.TransformerFactory > /dev/null 2>&1; \
        if [ $? -ne 0 ]; then \
           /home/shchiu/project/icedtea6-1.9.1/bootstrap/jdk1.6.0/bin/java
-version; \
          echo "*** An XSLT processor (J2SE 1.4.x or newer) is required" \
          "to bootstrap this build" 1>&2; \
          exit 1; \
        fi

and when i typed the instruction

I found out that there is no compilation error, I thought maybe it had
something wrong at link time, so i searched every location where libjvm.so is
and replaced them with a new libjvm.so artificially, and it worked correctly
finally.
It should be do automatically when I rebuilt it. 

Other system information such as build time and platform are at the end of bug
report.
