g.E('edge-id').valueMap() failed to run for java.lang.ExceptionInInitializerError

[ministat]

This bug can be reproduced without any configuration. Anyway, if you have configuration and some backends, this bug may be triggered randomly.

The root cause is there is initialization dependency circle for TypeDefinitionCategory and ModifierType. So, it has a workaround:

call "org.janusgraph.graphdb.types.TypeDefinitionCategory.TYPE_MODIFIER_DEFINITION_CATEGORIES" before "org.janusgraph.graphdb.database.management.ModifierType.values()"

For confirmed bugs, please report: Version: 1.0.0 Storage Backend: No specific backend Mixed Index Backend: none Link to discussed bug: none

Steps to Reproduce:

1. Download janusgraph-full-1.0.0 and decompression the package.
2. Start the gremlin: bin/gremlin.sh
3. Link to discussed bug: https://github.com/TheHive-Project/TheHive/issues/1429
4. run "org.janusgraph.graphdb.database.management.ModifierType.values()" in the console, and you will see "java.lang.ExceptionInInitializerError"

5. The workaround is: call "org.janusgraph.graphdb.types.TypeDefinitionCategory.TYPE_MODIFIER_DEFINITION_CATEGORIES" before "org.janusgraph.graphdb.database.management.ModifierType.values()" because there is initialization dependency circle for TypeDefinitionCategory and ModifierType.
