java - Will Proguard or the Compiler Precalculate TimeUnit.Minutes.toMillis(120) -

-

currently have class following effectively constant field.

private static final long activity_timeout_ms = 1 * 60 * 1000;

this fine, still not readable code in world. i'd rather use following:

private static final long activity_timeout_ms = timeunit.minutes.tomillis(1);

which states want time 1 minute field milliseconds.

my question either compiler or perhaps proguard fix there no performance hit? if there performance hit, can expect 1 time hit per instance of class?

yes, one-time hit on class loading, , such tiny fraction of class loading it's not measurable against overhead of loading class in first place.

no, compiler can't figure out, , surprised if proguard could, doesn't matter.

we using avaje-agentloader enhance our ebeans. ebeans in same package. including loader, agent & base ebean library in our project (via sbt): "org.avaje" % "avaje-agentloader" % "1.1.2", "org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.5.5", "org.avaje.ebeanorm" % "avaje-ebeanorm-agent" % "4.5.2", however, when loader runs enhancement, skips 1 ebean. each ebean annotated @entity , extends com.avaje.ebean.model . there seem no differences between ones enhanced , 1 not. there no includes, or extends, etc. basically, i'm wondering if has run across issue in past, or has insights. things we've tried: specifying actual classes enhanced via serverconfig.setclasses(...) specifying pakages analyse/enhance via serverconfig.addpackage(...) or setpackages(...) not specifying @ , having loader analyse all. we've set break-point @ transformer.transform , bean in questio...
