Code and Design Feedback request: 7114376: tune system dictionary size

[Karen Kinnear]

David,

Thank you for asking, my mistake. Here is an accessible webrev.

Webrev: http://cr.openjdk.java.net/~acorn/7114376/webrev/

An alternative possibility for supplying a single flag might be: -XX:LoadedClasses=#

This could be an anticipated count of expected total classes, which we could use
internally to set the initial SystemDictionary size. This might outlast any internal changes
in data structures.

Tests run:
vmsqe: nsk.quick.testlist: solaris-sparc, fastdbg - this includes sa testing
jck: vm,lang,api: solaris-sparc, fastdbg
JPRT - this includes CDS testing
performance runs in progress, including frequency of checking need to resize

thanks,
Karen
