I am using Virgo 3.6.0 which includes these Equinox bundles: - org.eclipse.equinox.cm_1.0.400.v20120319-2029 - org.eclipse.equinox.common_3.6.100.v20120509-1351 - org.eclipse.equinox.console_1.0.100.v20121001-124408 - org.eclipse.equinox.util_1.0.300.v20111010-1614 - org.eclipse.equinox.event_1.2.100.v20111010-1614 - org.eclipse.equinox.region_1.1.0.v20120319-1602
While deploying an app with about 50 bundles I get random ConcurrentModificationExceptions like the one below. Can you advise a debugging strategy? Thanks! java.lang.RuntimeException: java.util.ConcurrentModificationException: null at java.util.ArrayList$Itr.checkForComodification(Unknown Source) at java.util.ArrayList$Itr.next(Unknown Source) at
