mbien opened a new issue, #4500:
URL: https://github.com/apache/netbeans/issues/4500
### Body
This is somewhat related to #4140 (fixed via #4142 / NB 15) but the codepath
is different (see flamegraph).
when taking the FieldsOfJoy test as baseline and adding 10k methods to the
fields, completion performance suffers significantly (~10s). If the methods are
not there, completion finishes instantly thanks to #4142.
However: this is specific to static imports, it can't be reproduced with
normal usage
```java
//import static test.fields.FieldsOfJoy10k.*; // <- this is always fast
with NB 15
import static test.fields.FieldsOfJoy10k_many_methods.*;
public class Fields {
public static void main(String[] args) {
System.out.println( ); // use completion here, this is slow!
System.out.println(test.fields.FieldsOfJoy10k_many_methods.); //
this is fast!
}
}
```
thanks to @SirIntellegence for discovering this
(https://github.com/apache/netbeans/pull/4440#issuecomment-1213492886).
async profiler flamegraph shows that a significant time is spent in
`JavaCompletionTask.conflictsWithLocal` (this isn't the full graph, see
attached file below)
