# These source URLs are constructed from reading the
# acinclude.m4 and Makefile.in of icedtea:
# egrep '(^ *JDK_UPDATE_VERSION|^ *BUILD_VERSION)' acinclude.m4
#
# In icedtea you can choose between "default" and "zero" versions
# of the VM. The zero vm is meant for ARM based systems.
# Use this command to find out the hash of the hotspot.zip
# grep default hotspot.map

# Check ICEDTEA_BRANCH value in Makefile.in:
ICEDTEA_MAJOR="icedtea8"
ICEDTEA_BRANCH="3.33.0"
ICEDTEA_VERSION="3.33.0"
DROPURL="http://icedtea.classpath.org/download/drops"
SUPPURL="${DROPURL}/${ICEDTEA_MAJOR}/${ICEDTEA_BRANCH}"

# Get icedtea:
wget -c http://icedtea.classpath.org/download/source/icedtea-${ICEDTEA_VERSION}.tar.xz
wget -c http://icedtea.classpath.org/download/source/icedtea-${ICEDTEA_VERSION}.tar.xz.sig

# Get supporting sources:
wget ${SUPPURL}/openjdk-git.tar.xz -O openjdk_icedtea-${ICEDTEA_VERSION}.tar.xz

# Extract Makefile.in:
tar -O -xvf icedtea-${ICEDTEA_VERSION}.tar.xz icedtea-${ICEDTEA_VERSION}/Makefile.in > Makefile.in

# Get softwareversions from acinclude.m4:
tar -O -xvf icedtea-${ICEDTEA_VERSION}.tar.xz icedtea-${ICEDTEA_VERSION}/acinclude.m4 > acinclude.m4
