Knut Anders Hatlen commented on DERBY-5469:
-------------------------------------------
I see similar differences on Solaris. "ant -q all" takes ~40 s when JAVA_HOME
points to JDK 6, and ~65 s when it points to JDK 7. I also see this when
running without the patch, so I don't think there's a problem with the patch.
Another observation: If I remove the source="..." and target="..." attributes
from all the javac targets in the build files, the JDK 7 build runs as fast as
the JDK 6 build. Perhaps javac in JDK 7 is less optimized for compiling classes
with source and target level 1.4.
