Hi,

this seems to be a reproducible bug, at least I get it each time I tried:

If you mistype a Lombok Annotation (not sure with other annotations), you can get Netbeans to hang with full CPU usage on one core and multiple exceptions dumps in log file.


Works:
@Getter(onMethod = @__(@JsonValue))

Does not Work:
@Getter(onMethod = (@__@JsonValue))



Exception in Log-File:
java.lang.NullPointerException

Comment 1 Svata Dedic 2017-03-09 12:08:27 UTC 
Will not handle for 8.2 release, niche userbase. 

I've tested with current dev build and it seems that Lombok has serious problems with bundled nbjavac / JDK9 implementation. NPEs, linkage errors etc.
