Solution:

Let's make a small change in your WLS_HOME/common/bin/pack.sh to raise the used heap to 1Gb.

1) Copy WLS_HOME/common/bin/pack.sh to WLS_HOME/common/bin/packBACKUP.sh

2) Edit WLS_HOME/common/bin/pack.sh

Go to the empty line 95 and insert MEM_ARGS="-Xms1024m -Xmx1024m"

Change this section from:  

cd "${WL_HOME}/common/lib"
JVM_ARGS="-Dprod.props.file='${WL_HOME}/.product.properties' ${MEM_ARGS} ${CONFIG_JVM_ARGS}"

To this:

cd "${WL_HOME}/common/lib"
MEM_ARGS="-Xms1024m -Xmx1024m"
JVM_ARGS="-Dprod.props.file='${WL_HOME}/.product.properties' ${MEM_ARGS} ${CONFIG_JVM_ARGS}"

3) Save WLS_HOME/common/bin/pack.sh and exit

4) Retry the prepare phase
