UseJava: Use correct path separator in javadoc classpath
The correct path separator (":" on Linux and ";" on Windows) is used in the classpath of add_jar, but ":" is always used in the classpath of create_javadoc.
This patch uses the pattern from add_jar to determine which path separator to use.
Fixes: #19896 (closed)
