I'm having a weird stack overflow error with Neo4j, if someone could take a look I'd appreciate it.
I've been working on the GraphGist winter challenge, and my progress is here: https://gist.github.com/KevinGreene/8493604. If you run this in graphgist, there is a stack overflow error, so I tried running it against my local neo4j instance. If I run the entire 1200 lines of CREATE statements, it hangs at "Executing Query". If I run the first ~1100 lines, it succeeds. However, if I run the first ~1100 lines, delete all nodes / relationships, then run the entire 1200 lines, it succeeds. I've considered rewriting it to be more succinct, but I'm not sure that will fix the issue. Below is the start of the error from console.log: 14:27:46.678 [qtp372381930-59] WARN o.e.jetty.servlet.ServletHandler - Error for /db/data/transaction/commit java.lang.StackOverflowError: null at scala.collection.mutable.ListBuffer.$plus$plus$eq(ListBuffer.scala:176) ~[scala-library-2.10.3.jar:na] at scala.collection.mutable.ListBuffer.$plus$plus$eq(ListBuffer.scala:45) ~[scala-library-2.10.3.jar:na] at scala.collection.TraversableLike$class.to(TraversableLike.scala:629) ~[scala-library-2.10.3.jar:na] at scala.collection.AbstractTraversable.to(Traversable.scala:105) ~[scala-library-2.10.3.jar:na] at scala.collection.TraversableOnce$class.toList(TraversableOnce.scala:257) ~[scala-library-2.10.3.jar:na] at scala.collection.AbstractTraversable.toList(Traversable.scala:105) ~[scala-library-2.10.3.jar:na] at scala.collection.immutable.List$.apply(List.scala:400) ~[scala-library-2.10.3.jar:na] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query.compact(Query.scala:73) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query$$anonfun$tailQ$lzycompute$1$1.apply(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query$$anonfun$tailQ$lzycompute$1$1.apply(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at scala.Option.map(Option.scala:145) ~[scala-library-2.10.3.jar:na] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query.tailQ$lzycompute$1(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query.tailQ$1(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query.compact(Query.scala:82) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query$$anonfun$tailQ$lzycompute$1$1.apply(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query$$anonfun$tailQ$lzycompute$1$1.apply(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at scala.Option.map(Option.scala:145) ~[scala-library-2.10.3.jar:na] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query.tailQ$lzycompute$1(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query.tailQ$1(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query.compact(Query.scala:82) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] at org.neo4j.cypher.internal.compiler.v2_0.commands.Query$$anonfun$tailQ$lzycompute$1$1.apply(Query.scala:79) ~[neo4j-cypher-compiler-2.0-2.0.0.jar:2.0.0] -- You received this message because you are subscribed to the Google Groups "Neo4j" group.
