JavaPropsMapper doesn't close the .properties file properly after reading

[fcolmenarez]

When I read an object from a .properties file I can't delete the file, access is held by the JVM. The input stream isn't closed properly unlike the regular JSON parser which does close.

This came up in a scenario when we read a properties file to create the object and later needed to delete the file.

Only seems to happen under Windows 10 (Linux is NOT impacted). Java version is 8 using Open JDK 8 u242 b08.

Attached a zip file with a small maven project created in IntelliJ demonstrating the issue. Run "compile" to ensure the resources (.json, .properties files) are copied to the target folder before each run.

Thank you for reporting this, providing unit test. Will have a look.

Ah. Yes, I can see where this occurs. Just need to figure out best way to handle closing within JavaPropsParser, in appropriate cases (since there is special case of InputStream being passed, caller requesting stream not to be closed).
Ideally also need to see how to add an automated test case.

Glad to be of help. For now we are working around it by loading the properties file separately into a byte array in memory and pass that to the mapper (the files is small enough size is not a concern)

Fixed (with test reproduction), to be included in 2.10.4
