Added Testcase for Issue 135
Fix Issue 135: NPE while mapping to a nested property
Migrated eclipse tools to use recent versions of eclipse jdt
dependencies.
Fixed spelling error.
Removed separate alternate compiler strategy.
Merge branch 'master' of https://github.com/orika-mapper/orika.git
Added explicit pre-loading of hidden types.
Added a copy of tccl instead of using the existing tccl to isolate from
other tests.
Added javadocs
[maven-release-plugin] prepare release orika-parent-1.4.4
[maven-release-plugin] prepare for next development iteration
Added StateReporter and Reportable interface as infrastructure to help
provide state information on exceptions.
Added system property to dump state on exception (true by default) to
help with troubleshooting mapping issues.
Updated toString() on various builtin converters and generated object
types to provide better information for troubleshooting.
Added reportCurrentState method to DefaultMapperFactory,
MapperFacadeImpl and DefaultConverterFactory to be used when dumping
state on exception.
Added java-sizeof library dependency to provide memory usage estimates
along with report of current state.
removed junit imports from hidden runners
Update README.md
filtered out signature files to avoid runtime errors for inconsistent
jar signatures
added resolved strategy to MappingException for better error reporting
moved mapping strategy to main package to avoid circular dependencies
improved toString methods to report details more consistently
Made StateReporter.Reportable static, as it was not visible to outside
classes in current state
Added special handling of BidirectionalConverter to register in both
directions to ensure the proper converter is resolved.
Made deprecated 'BidirectionConverter' extend BidirectionalConverter for
consistency.
removed delegated equals and hashCode methods (else, reversed direction
cannot be added to registry as it will replace the forward version)
Don't register bidirectional converters in both directions if aType ==
bType.
Display fully-qualified types in MappingException
