JDK9 build failure on Windows : javac OutOfMemoryError

[Bradford Wetmore]

Phil,

That looks exactly like my problem.

Subject:  Heads Up:  OutOfMemoryError when building a 64-bit JDK 9 using 
a 32-bit bootdir.

I *BELIEVE* that for the bootdirs discovery (I haven't checked the 
code), if a JDK isn't given one with config's --with-boot-jdk, it 
defaults to whatever JDK is found in the path.  I typically only install 
a 32-bit one, as several applets I use require 32-bit only.

As for how much head is actually needed, I haven't dug into it, but just 
doing a simple javac -XmxXXXM Foo.java, I could only get up to about 
1500M.  I wasn't able to build on my laptop, but my lab machine worked 
just fine, so it's probably close to the border.
