Status in openjdk-lts package in Ubuntu:
  Confirmed
Status in openjdk-lts source package in Bionic:
  New

Bug description:
  When running an SWT ui with an embedded AWT/Swing component the
  library loading process fails as soon as the user clicks on a
  JComboBox.

  The error visible is: Inconsistency detected by ld.so: dl-lookup.c:
  111: check_match: Assertion `version->filename == NULL || !
  _dl_name_match_p (version->filename, map)' failed!

  running the JVM with LD_DEBUG=all exposes the /lib/libjawt.so as the source of the problem.

  ############
  A quick smoke test revealed that the package from adoptOpenJDK does not have the issue. I can also use the libjawt.so from adoptOpenJDK and run my SWT/AWT ui without any issues.
