com.fasterxml.jackson.core.JsonParseException(Invalid UTF-8 start byte) occured when using multibyte character

Question

I tried to save a node entity(@NodeEntity) whose property(string type) has multi-byte string like Japanese, but JsonParseException occurred.

java.lang.RuntimeException: com.fasterxml.jackson.core.JsonParseException: Invalid UTF-8 start byte 0x8d at [Source: [B@569cfc36; line: 1, column: 67]

But if I invoked java with -Dfile.encoding=UTF-8 option, a entity is saved correctly...

Please advice me how to save multi-byte string without -D=file.encoding option? I think that it is preferred that encoding is specified in config file or by coding.

Thanks.

My Environment is here.

OS=Windows 7 64bit(Japanese Edition)
Java=JDK1.8u121
Spring Boot=1.5.2
Spring Boot Neo4j=4.2.1
Noe4j Driver= Bolt Driver 2.1.2

This is a known issue in ogm - https://github.com/neo4j/neo4j-ogm/issues/244.

Current suggested workaround is exactly what you did - provide property at startup

-Dfile.encoding=UTF-8
