Description
To fix JDK-8012265 we bumped the default value of  HeapBaseMinAddress for G1 on Solaris x86 from 256m to 1g. Once we have reduce the amount of memory that G1 mallocs we should revert back to have the same default value for G1 as the other GCs.
Comments
As part of the fix for JDK-8013938 the G1 specific code was removed. Instead the HeapBaseMinAddress is now 2G for all GCs.
