Unable to start Neo4j. java.lang.NumberFormatException: null

[willmoss]

Hi,

I'm trying to run visualizer on Windows 7

I installed Neo4j Enterprise 1.8.3 and Java 6 (for backwards compatibility)

I started the server Neo4jCoordinator.bat

I run BlockViewer.jar with the following command

Y:\Documents\bitcoin\BitcoinVisualizer\server\jar>java -jar -Xmx512m BlockViewer
.jar -dbPath Y:\Documents\bitcoin\neo4j-enterprise-1.8.3\data\graph.db\ -configP
ath Y:\Documents\bitcoin\neo4j-enterprise-1.8.3\conf\neo4j.properties -validate
false -client

I'm getting the following error:

I took a look at the code, there seems to be some issue with the class HighlyAvailableGraphDatabase when initializing Neo4j. Unfortunately there is not a lot information around on the net about this class - it seems it may have been superseeded in Neo4j 1.9

I tried this on Windows & Linux, and got the same error.

Without a fix for this, the program is kinda unusable.

Cheers!
