Interesting. Further testing revealed that sun-jdk-1.5.0.11's behavior
is consistent on all amd64 procs. Despite earlier statements about it
not failing on Turions. Compiling Tomcat 6.0.x with 1.5.0.11 on amd64
fails always, less memory is increased or compiler is switched to ecj
from javac.

Beyond that 1.5 and 1.6 seem to have the same default allocations,
except for initial starting min value. 1.5.0.11 stars with like 4mb, and
1.6 starts with ~7mb. Their max is the same default. ~64mb on x86, and
~84-96mb on amd64.

But there still might be other things in the jvm that are undesirable
performance and etc wise in 1.5.0.x. Which they address in 1.6 or etc.
