RFR: JDK-8160571: Bootcycle builds still broken with server jvm on Windows 32bit

[Erik Joelsson]

In JDK-8160285 I tried to fix the bootcycle build on 32bit windows when 
only the server jvm is being built. It appears I only verified the fix 
on a release build. In my JPRT job I forgot to enable only the server 
jvm so it ran with client.

We are now faced with more similar failures in the fastdebug build. The 
javac server process is set to use mx1500M and fails all the time in 
that configuration. The JAVA_FLAGS_BIG config fails intermittently with 
not being able to allocate enough memory.

My suggested fix is to further reduce the maximum amount of heap from 
1100 to 1024 to avoid the intermittent failures and to replace the 
override of the "javac server jvm args" with the same set of args as 
have already been calculated for "java big". I have run this 
configuration through JPRT with client disabled. I have also run several 
builds locally without failure.
