Description

The luni module test tests.api.java.net.DatagramSocketTest seems to be unstable.

While iterative cc run tests.api.java.net.DatagramSocketTest failed 1 time out og 50:
test_connectLjava_net_InetAddressIClass: tests.api.java.net.DatagramSocketTest
junit.framework.AssertionFailedError: Failed to set up datagram server for native connected Dgram socket test
at tests.api.java.net.DatagramSocketTest.test_connectLjava_net_InetAddressI(DatagramSocketTest.java:299)
at java.lang.reflect.VMReflection.invokeMethod(Native Method)

Running the test separately:
#!sh
JRE_HOME=<PATH_TO_JRE>
A=0
while [ "$A" -lt "50" ]; do -
ant -Dbuild.module=luni -Dhy.test.forkmode=once -Dhy.test.vm.name=drl \
-Dtest.jre.home=$JRE_HOME \
-Dtest.case=tests.api.java.net.DatagramSocketTest test 2>&1 | tee test.log
R=`grep "BUILD FAILED" test.log | wc -l`
if [ "$R" = 0 ]; then
rm -rf build/test_report
else
mv build/test_report build/test_report_${A}
fi
A=`expr $A + 1`
done

I observed 2 more failures (also 1 time outof 50):

test_getPort Failure
unexpected exception during getPort test : The address is already in use
junit.framework.AssertionFailedError: unexpected exception during getPort test : The address is already in use at tests.api.java.net.DatagramSocketTest.test_getPort(DatagramSocketTest.java:672) at java.lang.reflect.VMReflection.invokeMethod(Native Method)

test_receiveLjava_net_DatagramPacket Failure
