eclipse java runtime error error

[C. Jeffery Small]

Eclipse was running properly under 17.10. After the upgrade to 18.04, attempts to start it produce the following error:

!SESSION Thu Jun 07 22:26:49 PDT 2018 ------------------------------------------
!ENTRY org.eclipse.equinox.launcher 4 0 2018-06-07 22:26:49.702

I have reinstalled all the eclipse and core java packages with no improvement.

eclipse 3.8.1-11
libcj-java 3.13.3-1
java-common 0.63ubuntu1~02
default-jre 2:1.10-63ubuntu1~02
default-jdk 2:1.10-63ubuntu1~02
