Karl Pauls commented on FELIX-5751:
-----------------------------------
Interesting, yes - please try to reproduce with 5.6.10. We don't deploy
snapshots regularly - hence, I'm unsure how recent that framework really is and
there have been some changes.
I'll try to look if I can see an easy way to synchronize that call in a cheap
way.

> Unclear whether there is anything Felix can do to fix or workaround this, but
> raising for info anyway...
> I am developing an application with Felix 5.7.0-SNAPSHOT (pulled from the
> Apache Snapshots repo, JAR built on Tue Nov 07 23:42:44 CET 2017).
> The nature of the application means that frequent calls are made to
> {{Bundle.getEntry()}}. Also because I am developing incrementally in
> Bndtools, the bundle is being updated frequently. Apparently as a result, I
> am getting JVM crashes every 5-10 minutes. The crash always happens in
> {{Bundle.getEntry()}}, specifically in the native
> {{getEntry(long,byte[],boolean)}} method of {{java.util.zip.ZipFile}}.
> It seems likely this is happening due to {{Bundle.getEntry}} being invoked
> concurrently with {{Bundle.update}}, so I wonder if Felix can implement any
> locking in this scenario? I have attached several hs_err files generated by
> the JVM.
> I am running Java 1.8.0_152-b16 on macOS Sierra (10.12.6 (16G29)). I have not
> yet replicated the crash with released Framework 5.6.10 but I am attempting
> to do so and will update this issue.
