Neil Bartlett commented on FELIX-5751:
--------------------------------------
Thanks for the J8 workaround, that will be helpful. I'm happy for the issue to
be resolved on that basis, since this doesn't seem to be likely to cause
problems in a production system.

> 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.
