it looks like that this commit 53438b9?w=1 . fix this NPM crash. is it? @Judds

[SZn007]

then I can only reback to 4.7.1 to fix the problem now?

[sjudd]

That looks plausible.

You could also use the latest snapshot: http://bumptech.github.io/glide/dev/snapshots.html

We are facing the same issue while we are using glide Version 4.9. Please confirm which version has fixed this issue. Because 4.9 seems to be the latest one. @sjudd

I have the same issue in my project when I update to 4.9

This is the highest firing crash in our app, it would seem prudent to do a patch release to fix it.

[AshishAccedo]

Why this issue status is closed, did anyone tried below version? where it seems looking fixed:

http://bumptech.github.io/glide/dev/snapshots.html

[jocoders]

Any news? I have the same issue on my app from crashlytics:
Fatal Exception: java.lang.NullPointerException Null reference used for synchronization (monitor-enter) com.bumptech.glide.load.engine.EngineResource.release
Please let me know.
