JDK11 & Polyglot

[Bob McWhirter]

With the new JDK11 changes, at one point I could build polyglot/libpolyglot
with JDK11.

Currently, though, I'm hitting:

Error: Image build request failed with exit status 1

Which when I add debug, can shuffle around and point to ObjectIdentifier or
TimerKeyImpl or a variety of other classes.

I sense that it might be the transient static boolean COMPACT_STRINGS on
String.class ultimately causing it, but that's not necessarily a warranted
opinion.  It always seems to be a String problem, and COMPACT_STRINGS is
designated as set by the JVM at runtime, not to the true that appears in
the source.

Anyone have a thought or a pointer on what might've changed in the past 3
weeks, or if I'm completely off base and would be willing to point me in a
more useful direction.

Thanks,
