I should also speicifically mention the the default sigin porlet fields would not allow data entry on OpenJ9 as well.

I went ahead and installed the latest Oracle JDK, jdk1.8.0_192, and it works fine with Liferay 7. So the problem seems to be with OpenJ9 itself

Liferay 7 and OpenJ9 fail to load themes

2018-10-30T20:14:49Z

In the advent of free support for Oracle JDK 8 ending in January I'm starting to look for alternatives. I thought I'd try running Liferay on Eclipse OpenJ9, specifically version jdk8u192-b12. I'm seeing an issue with the themes not loading. My Liferay log having messages like:
2018-10-30 19:43:53.572 WARN [http-nio-8080-exec-5][ThemeLocalServiceImpl:230] No theme found for specified theme id maintheme_WAR_signintheme. Returning the default theme.

In the osgi/state folder get a log file containing the following message:

I have several other Java based web apps and restful services that seem to run fine. I'd like to know if this an issue with OpenJdk in general or OpenJ9 specifically.

Any help or information will be greatly appreciated.
