Description

Bug reproduction uses Apache Ignite karaf feature with JDK 8. In this case org.apache.ignite.ignite-core plays host to fragment org.apache.ignite.ignite-indexing.

1) Expose

com.sun.management, \
sun.misc, \
sun.nio.ch

in system bundle

(for some reason ignite uses Import-Package to wire these so boot delegation is not enough; we need to append packages to system bundle)

2)

karaf@root()> feature:repo-add mvn:org.apache.ignite/ignite-osgi-karaf/2.6.0/xml/features
karaf@root()> feature:install ignite-core
karaf@root()> feature:install ignite-indexing

Works fine in 4.2.0 but in 4.2.1 this generates exception:

java.lang.ArrayIndexOutOfBoundsException: -1

	at java.util.ArrayList.set(ArrayList.java:450)

	at java.lang.Thread.run(Thread.java:748)
Error executing command: -1

Now this does not seem to happen with all fragment-host combinations. But the above example is a reliable way to reproduce the faulty behavior in Karaf 4.2.1.

This might be related to changes introduced in KARAF-5706 but as of yet undetermined.
