[ARIES-1381] java.lang.ClassCastException: org.apache.aries.subsystem.core.archive.GenericDirective cannot be cast to org.apache.aries.subsystem.core.archive.VersionRangeAttribute

• Type: Bug
• Status: Closed
• Priority: Minor
• Resolution: Fixed
• Affects Version/s: subsystem-2.0.2
• Fix Version/s: subsystem-core-2.0.4, subsystem-bundle-2.0.4
• Component/s: Subsystem
• Assignee: John Ross

Description

Example:
Import-Package: org.objectweb.asm;version:="5.0.4,5.0.4]",org.objectweb.asm.signature;version:="[5.0.4,5.0.4]",org.objectweb.asm.tree;version:="[5.0.4,5.0.4]"

This Import-Package header will cause a "GenericDirective cannot be cast to VersionRangeAttribute" error thrown by the ImportPackageHeader class.

This is caused by the fact that the custom version directive is interpreted as the version attribute by the getVersionRangeAttribute method.

What should have happened is:
1. The subsystem install should have succeeded.
2. The version should have been treated as a custom directive.
3. The actual package import versions would assume the default of [0.0.0,infinity) since a version attribute was not specified.
