---------------------------------------
Summary: Netbeans Java Editor fails to recognize java.sql module
types
Key: NETBEANS-6191
URL: https://issues.apache.org/jira/browse/NETBEANS-6191
Project: NetBeans
Issue Type: Bug
Components: java - Editor
Affects Versions: 12.2
Reporter: k thurston ng
Attachments: nebeans-platform-modules.png, netbeans-modules.png
*Product Version:* Apache NetBeans IDE 11.0 (Build
incubator-netbeans-release-404-on-20190319)
*Java:* 11.0.2; OpenJDK 64-Bit Server VM 11.0.2+9-LTS
*Runtime:* OpenJDK Runtime Environment 11.0.2+9-LTS
*System:* Windows 10 version 10.0 running on amd64;
I'm using the "Java with Ant -> Java Class Library" project template
In the Java Editor, when trying to use any of the classes included in the
java.sql module (e.g. java.sql.Connection, java.sql.DriverManager, etc.) - many
of the features of the java editor don't work.
auto-completion when importing java.sql.Connection (not a big deal, I can just
type it "manually"), but
if I Ctl-click on the import (to view source) - nothing happens
Similarly if I select the type and then go to view its JavaDoc in the JavaDoc
window, it displays "JavaDoc not found"
Note: I can build the project no problem, I can run Junit 4 tests – no problem
- so I'm fairly confident in my deduction that the ant scripts are not at
issue, and clearly the run-time system is able to find, load, and verify the
necessary types with no issue, so it's not as if my JDK image is at issue.
What I have noticed however, is that the java.sql module is not listed in the
project window, libraries:
!netbeans-modules.png!
So is there a problem with the "platform" definition:
!nebeans-platform-modules.png!
Sure seems not to be, the platform manager window lists java.sql as expected.
I realize that these "problems" (the editor vis a vis the project-window) may
be entirely unrelated. But what I have noticed is that I only encounter this
editor problem when it comes to types that are defined in modules that are
*not* listed/displayed in the project window (the problem is not restricted to
java.sql module, same goes for java.logging, and I'm sure many others).
This is a bit baffling; I used the jmod command line tool to look at the module
definitions for java.sql and say java.xml and I don't see anything that would
distinguish them and result in one (java.sql) being "unrecognized" and the
other (java.xml) being recognized by the editor/project window
I saw in the netbeans.conf file that there are a lot --add-opens and
--add-exports JVM parameters, and I tried to explicitly
--add-modules=ALL-DEFAULT, but that had no effect.
Also, the sources for java.sql are in the same .zip file as for all the other
sources, same for the javadoc - so it's not that the sources or javadoc are
missing - the same src.zip work fine, again, for all the types included in the
listed platform modules in the properties window.
I can only surmise that the netbeans code that, presumably using reflection,
lists all the "system" modules (which is used to populate the
property-window->Libraries) is somehow ignoring java.sql, java.logging, etc.
Although, again, I don't really see on what basis it privileges some modules
over others (and of course the same bug isn't afflicting the platform manager
window as shown above)
P.S. I've also encountered this exact same bug using Netbeans 12.2 and JDK-15
on another computer - so it's not specific to either the JDK or Netbeans
version; I also looked in the Netbeans log and couldn't find any message that
seems to relate to this problem.
