[11u] RFR 8234466: Class loading deadlock involving X509Factory#commitEvent()

[Aleksey Shipilev]

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8234466
  https://hg.openjdk.java.net/jdk/jdk/rev/6d386d360955

The patch does not apply cleanly to 11u, because of two things:

  a) The move jdk.internal.misc -> jdk.internal.access happens in JDK-8211122, and that one is
already rejected from 11u backports. So, I had to rewrite the uses back to jdk.internal.misc.*.

  b) Test fails to compile due to the ambiguity in JarUtils: createJarFile(Path,Path,Path...) and
method createJarFile(Path,Path,String...). I believe it is caused by referencing one of the
non-updated JarUtils [2]. Instead of choosing the another testlibary (which probably has the impact
on the signing code), I opted to call the method that was available:
 - JarUtils.createJarFile(Path.of(TEST_CLASS_PATH, jar.getFileName().toString()), xdir);
 + JarUtils.createJarFile(Path.of(TEST_CLASS_PATH, jar.getFileName().toString()), xdir, Paths.get("."));

11u webrev:

Testing: new test (still passes), tier1, tier2, tier3
