I can't reproduce this.  Have you overridden $(JAVAC) somewhere?  
Here is the test case I've used:

#! /bin/sh

# Make sure conditional Java works.
# Report from Braden McDaniel.

required=gcj
. $srcdir/defs || exit 1

set -e

cat >> configure.in << 'END'
AM_PROG_GCJ
AM_CONDITIONAL(WITH_JDK, true)
AC_OUTPUT
END

cat > Makefile.am << 'END'
JAVAROOT = $(top_builddir)/java

JAVA_FILES = MyClass1.java

if WITH_JDK
noinst_JAVA = $(JAVA_FILES)
endif

EXTRA_DIST = $(JAVA_FILES)
END

cat >MyClass1.java <<'EOF'
public class MyClass1
{
}
EOF

mkdir java

$ACLOCAL
$AUTOCONF
$AUTOMAKE
./configure GCJ=gcj
$MAKE

This error is ok.  Simply don't define JAVAROOT conditionally.
