Please warn Oracle Java8 VM has inline optimization error!
Dear Friends,
I just test ignite 1.7.0 with Oracle JDK8 with some occasional error on
adjacent calling on Cache Object setters, it seems some bytecode
optimization caused the passing parameter to be ignored on the subsequent
setter call.
e.g.
double w, p =0;
w = p =4.0;
askrec.setWin(w);
askrec.setPlace(p);
public void setPlace(Double p) {
assert p > 0 : "place <=0 " + p;
this.place = p;
}
### Excluding compile: my.own.AskRecord::setPlace
Exception in thread "main" java.lang.AssertionError: place <=0 0.0
at my.own.AskRecord.setPlace(AskRecord.java:225)
at my.trade.TradeManagerTest1.case6(TradeManagerTest1.java:336)
at my.trade.TradeManagerTest1.mainTest(TradeManagerTest1.java:489)
at my.trade.TM2.main(TM2.java:12)
I am using '-XX:-inline' to prevent this issue but still under verifying.
-Patrick, Yeh

Hi Patrick,
I was not able to reproduce this issue neither under 8u51 nor on 8u101
under Mac using your code. Can you share the reproducer which does not use
Ignite with us when it's available?

Val,
It's definitely not an ignite issue.
It's Oracle JDK8 TieredCompilation bug.
We may test the git source to reproduce this issue and I have consolidate
the reproducer.
I'll upload it to the git soon.

Hi,
This is interesting. What should I run in your test to reproduce the issue?
Can you create a JIRA ticket for it?

I think I solved this Java 8 optimization by '-XX:-TieredCompilation'
or change the code above not to use autobox during method call.
It's quite .....
e.g.
Double w =4;
Double p =4;
askrec.setWin(w);
askrec.setPlace(p);
public void setPlace(Double p) {
assert p > 0 : "place <=0 " + p;
this.place = p;
}

Hi Patrick,
Is there a test that reproduces the issue?
