** Description changed:

  [impact]
  
  tomcat9's ssl code includes:
  
  from org/apache/tomcat/jni/SSL.java:
  
      /* Return OpenSSL version number (compile time version, if version < 
1.1.0) */
      public static native int version();
  
  from org/apache/tomcat/util/net/openssl/OpenSSLEngine.java:
  
          if (SSL.version() >= 0x1010100f) {
              protocols.add(Constants.SSL_PROTO_TLSv1_3);
          }
  
  This leads to a compile-time dependency on OpenSSL versioning, to
  provide TLSv1.3 support.
  
  [test case]
  
- On a Bionic system, install tomcat9 and java jdk (e.g. default-jdk).
- 
- Then create this java program:
- 
- ubuntu@lp1854072:~$ cat Test.java
- 
- import org.apache.tomcat.jni.SSL;
- 
- class Test {
- public static void main(String argc[]) {
-  System.loadLibrary("tcnative-1");
-  System.out.format("SSL version 0x%x\n", SSL.version());
- }
- }
- 
- Compile and run it:
- 
- ubuntu@lp1854072:~$ CP="." ; for j in /usr/share/tomcat9/lib/*.jar 
/usr/share/tomcat9/bin/*.jar ; do CP="${j}:$CP" ; done
- ubuntu@lp1854072:~$ javac -cp $CP:. Test.java
- ubuntu@lp1854072:~$ java -cp $CP:. Test
- SSL version 0x1010100f
- 
- Note that the SSL version should match the newer libssl version.
+ TBD - checking with bug reporter
  
  [regression potential]
  
  as this is a rebuild-only, any regression would likely involve tomcat9
  behavior changes due to differing compile-time dependencies.
  
  [other info]
  
  This isn't technically a regression, as before OpenSSL was upgraded to
  1.1 in Bionic, tomcat9 correctly didn't provide TLSv1.3 support; but now
  that OpenSSL 1.1 is available in Bionic, tomcat9 should support TLSv1.3.
