OpenJDK 11.0.6 was released a couple of weeks ago and it seems to cause problems with Liferay CE 7.2.0 and 7.2.1 (and possibly also with older releases).

Looking into ${liferay_home}/work shows that subdirectories are created properly but there are no .java nor .class files.

An example with OpenJDK 11.0.6:

$ find work/com.liferay.login.web-4.0.8
work/com.liferay.login.web-4.0.8
work/com.liferay.login.web-4.0.8/org
work/com.liferay.login.web-4.0.8/org/apache
work/com.liferay.login.web-4.0.8/org/apache/jsp

same with OpenJDK 11.0.4:

$ find work/com.liferay.login.web-4.0.8
work/com.liferay.login.web-4.0.8
work/com.liferay.login.web-4.0.8/org
work/com.liferay.login.web-4.0.8/org/apache
work/com.liferay.login.web-4.0.8/org/apache/jsp
work/com.liferay.login.web-4.0.8/org/apache/jsp/login_jsp.class
work/com.liferay.login.web-4.0.8/org/apache/jsp/navigation_jsp.class
work/com.liferay.login.web-4.0.8/org/apache/jsp/navigation_jsp.java
work/com.liferay.login.web-4.0.8/org/apache/jsp/login_jsp.java

This seems to happen with all customized and Liferay's own .jsp files. Possibly an issue with the jsp -> java compiler.
