Summary: Parsing Bug in
org.apache.cxf.jaxrs.json.basic.JsonMapObjectReaderWriter: in-string "{"
Key: CXF-7496
URL: https://issues.apache.org/jira/browse/CXF-7496
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.1.12, 3.1.7
Environment: java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
Reporter: Alon Bar-Lev
Hello,
We have found incorrect parsing of "{" within JSON strings. It seems like the
parser searches for "{" and "}" regardless of string boundary.
A reproduction program is attached, using latest 3.1.12 version.
Thanks!
