oom at javadoc time

[Henri Gomez]

I raised 32bits instances memory from 1.5Gb to 2.5Gb and still failures :

In early build phase i could see :

JAVADOC_CMD = /NOT-SET/re/jdk/1.8.0/promoted/latest/binaries/linux-amd64/bin/javadoc
-J-XX:-PrintVMOptions -J-XX:+UnlockDiagnosticVMOptions
-J-XX:-LogVMOutput -J-Xmx512m -J-Xms512m -J-XX:PermSize=32m
-J-XX:MaxPermSize=160m -bootclasspath
/home/cijenka/workspace/openjdk8-lambda-standard-build/noarch/centos5-x86_64-builder/build/linux-amd64/classes

BTW, javadoc is using Did  -Xmx612m -Xms512m -XX:PermSize=32m
-XX:MaxPermSize=160m

Are they are hardcoded somewhere ?
