RFR (XXS): 8020123 Test gc/g1/TestPrintRegionRememberedSetInfo.java fails with "test result: Error. No action after @build"

[Thomas Schatzl]

Hi all,

  can I get a review for the the following tiny change?

In this case, jtreg complained with a "test result: Error. No action
after @build" message when trying to build/run it.

The cause for this issue has been the use of jtreg 4.0 to develop and
test it (where this error does not occur), but regression testing is
running jtreg 4.1 (where this is an error).

This has apparently been an error since the corresponding change has
been committed, but this error has been shadowed by another jtreg
problem.

Another issue is that this test does not have a @run statement, so the
test has never been run during regression testing.

The fix consists of replacing the @build line with a @run line; a
separate @build line is not needed as the test has no additional
dependencies that need explicit building.

I.e.

  * @test TestPrintRegionRememberedSetInfo
  * @key gc
  * @bug 8014240
  * @summary Test output of G1PrintRegionRememberedSetInfo
  * @library /testlibrary
- * @build TestPrintRegionRememberedSetInfo
+ * @run main TestPrintRegionRememberedSetInfo
