RFR: JDK-8025686 : (s) Update jdk repo netbeans projects to support NetBeans 7.4 for Java 8 support

[Mike Duigou]

Hello all;

When JDK-8006709 (http://hg.openjdk.java.net/jdk8/jdk8/jdk/rev/cff8d7768d72) was pushed it changed the default source level for the jdk project NetBeans projects to 1.8. This was a reasonable change since at this point there was already a small amount of Java 8 "-source 1.8" code in the jdk repo. Since that time the amount of source has increased. This change meant, unfortunately, that it was no longer possible to use a release version of netbeans as 7.3 did not support Java 8 source. Users wanting to use the jdk projects had to use either special lambda builds of NetBeans or the nightly dev builds. 

NetBeans 7.4 will support Java 8 source. This changeset adjusts the projects so that they are recognized by NetBeans. The same change also works with NetBeans dev and lambda builds.

In addition to updating the projects this change also adjusts the location where classes would be written (assuming that compilation from within NetBeans wasn't broken--it is currently broken). This change is incomplete in that it doesn't properly understand the SPEC variable from the new makefiles but at least it prevents writing output to the repo directory. This will be further cleaned up in JDK-8016210 (https://bugs.openjdk.java.net/browse/JDK-8016210)

Cheers,

Mike
