Building OpenJDK libraries using IcedTea Project for JamVM

[Roman Davidenko]

".... if you just want a CACAO build, all you need is --enable-cacao and the build will download and use the right zip for you..."I did this already (with CACAO) and got `JVM_FindClassFromCaller'. I think I will get the same with the current stable 1.5.4 release of JamVM, the build will download I guess. Am I right? That's why I'd like to use the JamVM's current snapshot 2.0.0 that is, I guess, free of   "JVM_*" symbol issue.
Also, how about this:mkdir icedtea-buildcd icedtea-build../icedtea-2.5.3/configure --prefix=/var/www/icedtea-2.5.3 --disable-Werror --disable-system-gio --disable-system-kerberos --disable-system-jpeg --disable-system-gif --disable-system-lcms --disable-compile-against-syscalls --disable-native-debuginfo --disable-java-debuginfo --disable-docsmakethe build is fine# /var/www/icedtea/icedtea-build/openjdk.build/bin/java -versionjava version "1.7.0_71"OpenJDK Runtime Environment (IcedTea 2.5.3) (RedHatEnterpriseServer build 1.7.0_71-b14)OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)but[root at tawzee icedtea-build]# make installmake: Nothing to be done for `install'.RegardsRoman
