Jinterface Release Notes

## 1 Jinterface Release Notes

This document describes the changes made to the Jinterface application.

### 1.1 Jinterface 1.3

#### 1.1.1 Fixed Bugs and Malfunctions

- `OtpMbox.receive()` and `OtpMbox.receive(long timeout)` can now throw `OtpErlangDecodeException` if the received message can not be decoded. `null` is now only returned from `OtpMbox.receive(long timeout)` if a timeout occurs. `OtpMbox.receive()` will never return `null`.
  *** POTENTIAL INCOMPATIBILITY ***
  Own Id: OTP-3932 Aux Id: seq5196
- Strings longer than 65535 bytes were encoded wrong by jinterface.
  Own Id: OTP-4883 Aux Id: OTP-4865
- Misc bugfixes:
  - A node pinging itself does no longer cause the java program to hang.
  - `OtpMbox.close()` uses exit reason `'normal'` (atom) instead of `"normal"` (string).
  - Added `OtpNode.closeMbox(OtpMbox mbox, OtpErlangObject reason)`.
  - Added `OtpMbox.exit(OtpErlangObject reason)` and `OtpMbox.exit(String reason)`.
  - Added `OtpMbox.exit(OtpErlangPid to, OtpErlangObject reason)`.
  - `OtpMbox.exit(OtpErlangPid to, String reason)` is now equivalent to `OtpMbox.exit(to, new OtpErlangAtom(reason))`.
  - Exit signals from an Erlang node can now contain any erlang term as reason, not only atoms.

- For java versions 1.3.1 or later, `localStatus` was not sent to registered status handler when `OtpNode.close()` was called. This is now corrected.

#### 1.1.2 Improvements and New Features

- Process identifiers and port identifiers have been made more unique. Previously 18 bits were used as id in the internal representation of process and port identifiers. Now 28 bits are used.
  The maximum limit on the number of concurrently existing processes due to the representation of pids has been increased to 268435456 processes. The same is true for ports. This limit will at least on a 32-bit architecture be impossible to reach due to memory shortage.
  NOTE: By default, the `ERTS`, and the `erl_interface`, `ei`, and `jinterface` libraries are now only guaranteed to be compatible with other Erlang/OTP components from the same release. It is possible to set each component in compatibility mode of an earlier release, though. See the documentation for respective component on how to set it in compatibility mode.

### 1.2 Jinterface 1.2.1.2

#### 1.2.1 Fixed Bugs and Malfunctions

- Output of Java long was truncated to 32 bits. IDL long long and unsigned long long could not be used in a struct for the Java backend. All unsigned integer types for the Java backend had broken marshalling for large values. These bugs has now been fixed.
