RFR: JDK-8136893: Improve early java.lang.invoke infrastructure initialization

[Paul Sandoz]

Hi,

This looks like a partial dup of https://bugs.openjdk.java.net/browse/JDK-8076596

The changes look ok, but I am concerned post initialization there may be code paths taken that require the system class loader to be used but instead the boot stream class loader is used instead. Is that a legitimate concern?

Paul.

Its name does not suggest in any way that it chooses the class loader differently. The name is subtly different from that of fromDescriptorString(), and the signature is identical - it's probably really easy to confuse the two when working at the core libs level. Unfortunately, the only proposal for a name I can make, fromDescriptorStringBootCL(), is clunky. Maybe that's acceptable for a low-level method only visible at package level.
