RFR (M): First JTREG Tsan test

[Man Cao]

I couldn't run this test with "make run-test
TEST="jtreg:test/hotspot/jtreg/tsan/RacyIntMemberLoopTest.java"", I got the
following messages:

Test selection 'jtreg:test/hotspot/jtreg/tsan/RacyIntMemberLoopTest.java',

TEST SUCCESS

If I run "make run-test
TEST="jtreg:test/hotspot/jtreg/gc/TestNoPerfCounter.java"", it will show
something like:

Running test 'jtreg:test/hotspot/jtreg/gc/TestNoPerfCounter.java'

Test results: passed: 1

   TEST                                              TOTAL  PASS  FAIL

Is there anything I'm missing here to run this test?

Below are code comments:

In RacyIntMemberLoopTest.java

48           .shouldMatch("(Read|Write) of size 4 at 0x[0-9]+ by
thread T[0-9]+")

"0x[0-9]+" might be wrong to match an address. Should it be
"0x[0-9a-fA-F]+" or just "0x.+"?

Nit:
The test name typically does not end in ".java".
/* @test RacyIntMemberLoopTest.java
