RFR: JDK-8205508: hotspot/jtreg/vmTestbase/nsk/jdb/exclude/exclude001/exclude001.java fails with Prompt is not received during 300200 milliseconds.

[Gary Adams]

The first time I looked into problems with exclude001 test,
we discovered a large number of new packages in the jdk.internal
classes that were introduced in jdk9. The test needed to add excludes for
any of the jdk.* methods or it could not finish in time.

As a follow up I'll try a test run with unlimited time and no methods 
excluded to get
a specific count of methods that are being processed. Over time new 
features
have been added, e.g. string concatenation optimizations, lambda functions,
etc., etc., etc. For a test that does method tracing, each new method 
adds to the
collective time. If you can  not reduce the number of methods called, 
then the time
for the test needs to be increased.
