Does your tool jsonSchema2pojo work with JDK6 or less

[sashivit]

We are using Java 6 in our applications.

We wish to use your code to create and load the POJO classes.

While running your code, we are getting below error

jcvas$ jsonschema2pojo --source bss.cha.balanceEnquiryResponse.6.json --target java-gen

This should be fixed if we update the Jackson dependency to 2.7.2:

FasterXML/jackson-databind#1134

@thachhoang Excellent, thanks for investigating.
