[8u] RFR bad source/target in Makefile of J2DBench

[Jiri Vanek]

http://cr.openjdk.java.net/~jvanek/bad_j2d_bytecodeversion/

Hello! the build.xml (https://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/d2bbff5b7006/src/share/demo/java2d/J2DBench/build.xml#l52) is corerect,
and have -source/target correctly on 1.5

However Mkaefile was left behind, and is on 1.2, which jdk8 itself can not play.


Am looking forward for kind soul to create a bug a commit on my behalf.

Happy hacking,
    J.
