[GitHub] [netbeans] errael opened a new issue, #4651: Java hints disabled by exception; Java Platforms has bad entry
errael opened a new issue, #4651:
URL: https://github.com/apache/netbeans/issues/4651
### Apache NetBeans version
Apache NetBeans 15
### What happened
No hint highlights after exception in hints processing
### How to reproduce
(These steps reproduce 100% for me. I can provide the project and tainted userdir if that would be useful)
I narrowed down the issue with these steps. Once there's a userdir that has the problem, just start NB and get the exception
- staring with clean .nb/15 (some -J-D added to netbeans.conf)
- start nb, no imports
- open project, java file; note visible hints highlights
(not all projects exhibit the problem)
- import from "tainted userdir", restart
categories: general, miscellaneous (need both)
- OBSERVE: no hints, exception (see below)
In Java Platform Manager there are several entries, the entry `Zulu 18.0.2.1+1`
is shown in red. Select it and the following for PlatformInstallFolder:
```
/junk/Downloads/zulu18.32.13-ca-jdk18.0.2.1-linux_x64/zulu18.32.13-ca-jdk18.0.2.1-linux_x64
```
is displayed in red, and there's the message `Error: the specified folder does not contain a java platform`
Restart NB and the problem persists.
Remove this bad entry, and the hints show up again.
NOTE: the project does not reference this JDK.
I wonder if Platform is providing garbage to HintProcessing, or if HintProcessing is not handling a valid return from Platform.
I can see how importing miscellaneous is required, I wonder what's in General that's needed to trigger it.
FYI: While doing some cleanup I moved the referenced directory to where all the jdk's on this system reside, and forgot about it. Several days later, after changing and moving around lots of stuff locally, I noticed there was a hints problem.
```

Nuking the data might work, but I don't like the idea. If the Platform is an object, it should have an `isValid()` method. And something around hints/parser should be checking it.

Do you have any other project open that references the bad platform entry? Set in any of the global options? I was looking at other parsing errors recently, and noticed errors in code and paths for other opened (but unrelated) projects affecting things.

So in java/java.platform/.../JavaPlatform, there's already
```
public boolean isValid() {
return !getInstallFolders().isEmpty();
}
```
So it's down to finding what is using an invalid JavaPlatform.

I noticed something like this myself. I wrote some notes down that broken entries in the java platforms list can potentially stop the hints engine from working. I once had a JDK build registered which i built myself locally and problems started when i cleaned that build even though it wasn't even used in that particular project.

After the restart after the import of `General` and `Miscellaneous` the projects window says
```
<No Project Open>
```
Subsequent restarts have the same situation, no project open and hints exception. Attaching log

There's `userdir/config/Services/Platforms/org-netbeans-api-java-Platform/Zulu_18.0.2.1_1.xml` which is full of data even though it should be considered invalid, consider the ERROR color in the `Java Platforms` dialog because it can't file the file, didn't see where things got set to red. Looks like the In the log there's
```
WARNING [org.netbeans.modules.java.j2seplatform.platformdefinition.J2SEPlatformImpl]:
No sun.boot.class.path property in platform Zulu 18.0.2.1+1, broken platform?
```
In `J2SEPlatformImpl` there's `getJ2SEPlatformDefaultSources` which serves up the platforms.
Consider that the platform's dialog says
```
Error: The specified folder does not contain a Java platform.
If you want to specify a different folder for this platform, remove this platform and
create a new one with exactly the same name pointing to the correct platform folder.
```
I'm wondering if stripping everything from a platform xml file that doesn't have an install directory, except a few things that it could display that it's broken. I sure seems like the hint processor thinks it's working with a real jdk installation.
