ValueParser - UnsupportedOperationException with commons-beanutils 1.8
----------------------------------------------------------------------
Key: VELTOOLS-107
URL: https://issues.apache.org/jira/browse/VELTOOLS-107
Project: Velocity Tools
Issue Type: Improvement
Components: GenericTools
Affects Versions: 2.0
Environment: commons-beanutils 1.8
Reporter: Martin Thelian
Priority: Minor
As defined in [1], VelocityTools requires commons-beanutils 1.7 as a
dependency.
But because I'm running velocity in an OSGi environment and common-beanutils is
delivered as an ready-to-use OSGi bundle as of version 1.8, I've tried to run
Velocity-Tools 2.0-beta2 with common-beanutils 1.8 and I'm getting the
following Exception:

It would be fine if Velocity would work with Common Beanutils 1.8.0
