Guava, Graal and Partial Escape Analysis

Recently java 10 release happened - in fact, Graal was available earlier, but now it is more easy to access and use it - Congratulations, you're running #Graal! - just add a couple options:
-XX:+UnlockExperimentalVMOptions -XX:+UseJVMCICompiler
What does it can provide for us and what kind of enhancements we can expect to get, and more over - what dirty-hacks could be dropped ?

build hsdis with Java 10 on MacOsX

instructions to build hsdis with java 10 - based on instructions for building hsdis on OSX (with java 9)
$ hg clone http://hg.openjdk.java.net/jdk/jdk10/
$ cd jdk10/src/utils/hsdis
$ wget https://ftp.gnu.org/gnu/binutils/binutils-2.28.tar.bz2 
$ tar jxf binutils-2.28.tar.bz2
$ make BINUTILS=binutils-2.28 ARCH=amd64
$ sudo cp build/macosx-amd64/hsdis-amd64.dylib /Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home/lib/server
Note: despite of hsdis/README it does NOT compile with binutils-2.17, nor binutils-2.19.1 neither with latest binutils-2.30. binutils-2.28 works fine on High Sierra.
