Small update:
http://cr.openjdk.java.net/~vlivanov/8058892/webrev.01/
Need to reorder initialization sequence in MHI.Lazy. Initialized
FILL_ARRAYS and ARRAYS are required for later MH lookups.
Additional testing:
* jck (api/java_lang/invoke)
* jdk/java/lang/invoke, jdk/java/util/streams w/ "-ea -esa" and
COMPILE_THRESHOLD={0,30}
Best regards,
Vladimir Ivanov

Core j.l.i classes are preloaded during VM startup in order to avoid
possible deadlock when accessing JSR292-related functionality from
multiple threads. After LF sharing-related changes, FILL_ARRAYS and
ARRAYS are initialized too early. It affects startup time & footprint of
applications that don't use JSR292.
The fix is to move these fields into MHI.Lazy class, thus delaying their
initialization to the first usage of JSR292 API.
Testing: failing test, manual (measured HelloWorld app startup time;
compared -XX:+PrintCompilation logs)
Best regards,
Vladimir Ivanov
