Java.class.path, Jar files and directory expansion.

[ed03875]

This problem presents on W64 and Linux in two different distributions of OpenJDK Java 11 that we know of : openjdk version "11.0.2" 2019-01-15 and openjdk version "11.0.1" 2018-10-16.

I must be missing something obvious because I would have thought that others would have found this behaviour long before now. When starting the JVM and setting the system property java.class.path to point to directories and not specific jar files as shown here "-Djava.class.path=C:\directory\rmeval;.c:\fixes\bin\w64\bin\jvm\ext;" we find that classes that are known to be in the jars in the directories are not found. If we point to the jar specifically , the classes are found. Wildcards also have the same problem. for example "-Djava.class.path=C:\directory\rmeval*.jar;.c:\fixes\jvm\ext*;"

Has this functionality been removed from Java 11 ? We have a rather large product where it is not reasonable to specify each jar file used on the class path.
