Is it possible to extract the reproducible test case from your sources? Thanks.

I don't remember which source-code this exception came from. I'll let you know if I run across this error again.

Dusan,

SUCCESS!! I finally found a way to reproduce this bug :)

Using:

Product Version: NetBeans IDE Dev (Build 201505080001)
Java: 1.8.0_45; Java HotSpot(TM) 64-Bit Server VM 25.45-b02
Runtime: Java(TM) SE Runtime Environment 1.8.0_45-b14
System: Windows 7 version 6.1 running on amd64; Cp1252; en_US (nb)
User directory: C:\dev\Netbeans\user\dev
Cache directory: C:\dev\Netbeans\cache\dev

Repro steps:

1. Open the testcase.
2. Select GetPolicyPropertyIdValidator.java
3. Hit CTRL+C to copy the class
4. Enter the name SetPolicyPropertyIdValidator
5. Click OK
6. Wait a few seconds... 4-5 exceptions will get thrown. The last one is "java.lang.AssertionError: isSameType UNKNOWN"

Dusan,

Have you had a chance to try the attached testcase? Can you reproduce the problem on your end?

What do you mean here?

Sorry, let me know if this helps:

3. Select the class in the Projects tab, hit CTRL+C
4. Select the enclosing package in the Projects tab, hit CTRL+V. When prompted for the new class' name, enter "SetPolicyPropertyIdValidator"

(In reply to _ gtzabari from comment #9)
> When prompted for the new class' name, enter "SetPolicyPropertyIdValidator"

Error: Class "SetPolicyPropertyIdValidator" already exists in the target package.

But I did reproduce when I first deleted the file from your project and then followed your steps.

Comment 12 _ gtzabari 2015-10-07 21:16:25 UTC
Do you still plan on fixing this in version 8.1? If so, please read my comments in http://statistics.netbeans.org/analytics/detail.do?id=215572. If not, please update Target Milestone.

Inserting conflict markers into the file doesn't seem to trigger the exception by its own. In my case, this seems to be triggered by external file edits.

Comment 14 _ tboudreau 2016-08-29 09:23:27 UTC
FYI, I have a reliable way to reproduce it outside NetBeans:

1. Build contrib/classgraph
2. Get the sources (Oracle internal) to PGX from ssh://$YOUR_ID@ol-scm:/repos/projectq/pgx.git
3. cd into the source folder and run

java -jar /path/to/callgraph-jar-with-dependencies.jar -n -o /tmp/methods.edges -v .

Not sure, probably something to do with adding an if statement before a decleration. Totally nuked autocomple ...

Ok so there are different bugs going on here. The first is

   at com.sun.tools.javac.code.Types$SameTypeVisitor.visitType(Types.java:1121)'

The one from 2017-05-08 is 

	at com.sun.tools.javac.code.Types$SameTypeVisitor.visitType(Types.java:1283)


Not sure if you want me to file a different report? I have a dump file that was requested... 

From looking in the logs, I think the 1283 one resulted from a

java.lang.NullPointerException
