RFR: 8258525: Some existing tests should use /nodynamiccopyright/ instead of the standard header [v2]

[Guoxiong Li]

> Hi all,
> 
> This is the background of this patch. According to the comments[1] written by Jonathan Gibbons during the review of JDK-8231622[2], I want to solve previous tests that used the bad style. I wrote a python script[3] to find the bad style tests. But it is not precise and complete.

> Currently, I write another python script that can accurately check all the bad style tests. The procedure of this script is shown below.
> 1.  Add a blank line at the head of the java source files(exclude the files contain `/nodynamiccopyright/`) in directory `test/langtools/tools/javac`. This step simulates the changes of the length in the legal header.
> 2. Run the test by using the command `make test CONF=linux-x86_64-server-release JOBS=4 TEST=test/langtools/tools/javac`. This step checks whether the tests can be comfortable to the changes of the length in legal header. If a test failed, it means the test style is bad and need to be revised.
> 3. Delete the blank line at the head of the java source files(exclude the files contain `/nodynamiccopyright/`) in directory `test/langtools/tools/javac`. This step recovers the modified files.
> 
> If all the tests are in good style,  all the tests in step 2 will passed. I use this script to test the branch `master` locally. 129 tests failed. I fixed them. Currently, I use this script to test the branch `test-copyright-clean` of this patch locally. All the tests passed.
> 
> I think this patch solves all the bad style tests if my script has no bugs and no new bad style tests were integrated to branch `master` recently.
> 
> The code of the new python script is shown below. You maybe need to revise the options `CONF=linux-x86_64-server-release` and `JOBS=4` when testing locally.
