RFR: 5050783: Throwable convenience method: String getStackTraceString()

[Ivan St. Ivanov]

Hello,

I am Ivan from the Bulgarian Java User Group. As part of our Adopt OpenJDK
efforts, we organized hackathon beginning of this month in Sofia. There we
worked on the following JIRA issue:

https://bugs.openjdk.java.net/browse/JDK-5050783

Unfortunately none of us has author privileges, so the issue is still
unassigned. But, nevertheless, our JUG has already signed JSPA and some of
our members (including myself) have signed OCA. And we informed in a
special email this mailing list about our plans prior to the meeting.

Our hackathon was already documented by our JUG member Mihail Stoynov:

We used the days after the meeting for offline polishing our contribution
and adding some more unit tests. Here is the result of our work:

We would be very happy if you are able to review it, share your feedback
and guide us through the contribution process as this is our first attempt.

Thanks and have a very successful year!
Ivan
