        Description

        java/util/stream/test/org/openjdk/tests/java/util/stream/FlatMapOpTest.java

        Test fail due to time out in different runs, at different machine. Most often on Solaris Sparcv9.

        Here's one example from JDK9/b55 promotion testing:

        This run is on a Solaris 10, Sparcv9 1504 MHz, 2 cores, 2G machine. (But timeout also happens on other machines with 4 cores, 32G)

        This run uses jtreg options:
        -conc:2 \
        -vmoption:-Xmx768M \
        -javaoption:-Xmixed -javaoption:-d64 -javaoption:-server \
        -javaoption:-XX:+UseG1GC \
        -timeout:3 \
        -agentvm \

        As all java/util/stream tests are in exclusiveAccess.dirs (Tests that cannot run concurrently), -conc:2 should not matter.

        See the log details:
