1367027 - Signature for java crashes are too accurate

Status: RESOLVED FIXED

(Socorro :: General, task)

Description

[Calixte Denizet (:calixte)]

All the crashes returned by the query [1] are the same but since the signature contains the length of the ArrayList then they're all differents.
So we should remove this kind of info (eg length, index) and probably add the first function, before ones in java.*, which is in org.mozilla.*. It could be something like [@ java.lang.ArrayIndexOutOfBoundsException at java.util.ArrayList.get(ArrayList.java) | org.mozilla.gecko.home.activitystream.StreamRecyclerAdapter.onItemClicked(StreamRecyclerAdapter.java)]

and probably ones in android.* and dalvik.* as well?

On example crash report for that would be https://crash-stats.mozilla.com/report/index/917a221d-82b6-4264-8880-83e840171227#tab-details.

I haven't looked into this bug, but I just landed a change that drops the exception message from the signature. The query url in the description doesn't bring anything up, so I can't tell if it helped here or not.

Any idea if it helped? Is there more I should do here?

I updated the query:
https://crash-stats.mozilla.com/search/?signature=%40%22java.lang.ArrayIndexOutOfBoundsException%3A%20length%3D%22%5B0-9%5D%2B%22%3B%20index%3D-%22%5B0-9%5D%2B%22%20at%20java.util.ArrayList.get%28ArrayList.java%29%22&product=FennecAndroid&date=%3E%3D2018-04-08T17%3A51%3A50.000Z&date=%3C2018-10-08T17%3A51%3A50.000Z&_sort=-date&_columns=signature#crash-reports
The signature facet is still showing different signatures for different pairs (length, index).

Awesome! I reprocessed the crash reports in that query and now it shows "no results". So I think we're good here. Marking as FIXED.
