RFR: JDK-8194762: JTReg failure of "runtime/NMT/PrintNMTStatistics.java"

[stewartd.qdt]

Please review this small webrev [1] that removes the search for the word "error" in stdout for the PrintNMTStatistics during the NativeMemoryTracking=details sub-test of the JTReg test.

I have found that on my test machine (AArch64, Linux) when the detailed list is printed there is a module called "LogOutputList" that has as one of the listed functions "_dl_catch_error". Since the HTReg test simply searches for the word "error" in stdout, this test fails. However, there really isn't a failure to behave correctly and all the details are printed correctly. It also returns 0 on exit, as it should. The full log is attached to the bug report.

I have created this patch in the belief that the test is being overly restrictive in searching for "error" In stdout and that printing out "_dl_catch_error" is correct behavior and shouldn't cause the test to fail.

Please let me know if this is a bad approach and I'll be happy to change as required.

Thanks,
Daniel Stewart
