[Htmlunit-user] Error: cannot find symbol after fresh install of HtmlUnit

[Serg R. <rr...@ya...>]

Hello all
I'm new user, just downloaded and set-up
HtmlUnit in the first time.
1) 
My classpath set up as follows:(and all the jars are in this folder D:\java\jar\htmlunit\)
set CLASSPATH=C:\jdk9\bin\;C:\jdk9\jre\bin\;C:\jdk9\lib\;d:\java\servlet.jar;d:\java\JAVAX\;D:\CosmosLib\;D:\java\jar\htmlunit\commons-codec-1.10.jar;D:\java\jar\htmlunit\commons-io-2.6.jar;D:\java\jar\htmlunit\commons-lang3-3.7.jar;D:\java\jar\htmlunit\commons-logging-1.2.jar;D:\java\jar\htmlunit\commons-net-3.6.jar;D:\java\jar\htmlunit\commons-text-1.3.jar;D:\java\jar\htmlunit\htmlunit-2.31.jar;D:\java\jar\htmlunit\htmlunit-core-js-2.31.jar;D:\java\jar\htmlunit\htmlunit-cssparser-1.0.0.jar;D:\java\jar\htmlunit\httpclient-4.5.5.jar;D:\java\jar\htmlunit\httpcore-4.4.9.jar;D:\java\jar\htmlunit\httpmime-4.5.5.jar;D:\java\jar\htmlunit\jetty-client-9.4.10.v20180503.jar;D:\java\jar\htmlunit\jetty-http-9.4.10.v20180503.jar;D:\java\jar\htmlunit\jetty-io-9.4.10.v20180503.jar;D:\java\jar\htmlunit\jetty-util-9.4.10.v20180503.jar;D:\java\jar\htmlunit\jetty-xml-9.4.10.v20180503.jar;D:\java\jar\htmlunit\neko-htmlunit-2.31.jar;D:\java\jar\htmlunit\serializer-2.7.2.jar;D:\java\jar\htmlunit\websocket-api-9.4.10.v20180503.jar;D:\java\jar\htmlunit\websocket-client-9.4.10.v20180503.jar;D:\java\jar\htmlunit\websocket-common-9.4.10.v20180503.jar;D:\java\jar\htmlunit\xalan-2.7.2.jar;D:\java\jar\htmlunit\xercesImpl-2.11.0.jar;D:\java\jar\htmlunit\xml-apis-1.4.01.jar;.
2)
Have this line to import htmlunit package:
import com.gargoylesoftware.htmlunit.*;

3) 
Put this line in my java code (from example):
final HtmlPage page1 = webClient.getPage("http://...login_2.html");

However, compliling under Java 1.9 gives this error
for this particular line:error: cannot find symbol HtmlPage page1 = ....
                          ^
Cannot figure out, why it is not imported.
Could you help.
Thank you
Serg
