Hello again, colleagues. I would like to discuss couple of diffs.<br>
<br>
1.) Conversation about minor fix of <a moz-do-not-send="true"
href="https://bugs.openjdk.java.net/browse/JDK-8020129">JDK-8020129</a>
faded out. Let's return to it. As far as I recall Mikael Gerdin
agreed to sponsor this commit. Is it correct, Mikael? Link to
webrev is in "reply chain" below, but I am duplicating it: <a

<br>
2.) In scope of <a moz-do-not-send="true"
href="http://wiki.se.oracle.com/display/JPG/Native+memory+allocation+test+plan">test
plan</a> about native memory allocation I wrote three tests on
ReservedSpace/VirtualSpace. Find webrev here: <a

Could someone provide feedback and sponsor this commit as well?<br>

The JFR implementation require some heap and could cause
unexpected OOM during initialization. <br>
I think it is needed to verify that test pass with following
options: <br>
-XX:+UnlockCommercialFeatures -XX:+FlightRecorder
-XX:FlightRecorderOptions=defaultrecording=true,disk=true,dumponexit=true
-XX:ReservedCodeCacheSize=256M <br>

According to summary tag goal of test is to test that
OutOfMemoryError will be thrown, so there are no reason to
restrict Xmx value. We can impose 10Mb instead of 25Mb,
but this only means that we will increase it again in 10
years instead of 20 years - when running vm with -Xmx200Mb
will look as silly as running with -Xmx2mb now. :) <br>
<br>
@summary Check if the VM properly throws OutOfMemoryError

Does increasing -Xmx from 2m to 25m seem to be too
generous? How about 10m or some smaller value? That way,
the test can have enough pressure on the heap. <br>
<br>
BTW, the original author of the java test file looks CEO
of cloud.com. <br>
<br>
Thanks. <br>

Right, suggestion is to increase from 2M up to 25M. <br>
It seems to me that it's rather footprint of jdk that
increased as we are getting OutOfMemoryError in heap:
<br>
<br>
java.lang.OutOfMemoryError: Java heap space <br>
at InfiniteList.<init>(InfiniteList.java:9)
<br>
at InfiniteList.main(InfiniteList.java:12) <br>
<br>
<br>
I increased up to 25M to be sure it's enough. It
doesn't mean footprint increased 12.5 times. <br>

Does the need to increase Xmx for this test indicate
that <br>
we've increased the footprint of the JVM
significantly? <br>
The change in Xmx was from 2M to 25M, right? <br>
