Resolution: Won't Fix
Yeah I agree - still useful to know. Thanks for reporting!

> 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.
