| Apache BSF 3.1 Release Notes |
| ---------------------------- |
| |
| Apache BSF 3 is an open-source implementation of JSR-223, |
| "Scripting for the Java Platform". |
| |
| *----------------------------------------------------------------------* |
| * BSF3 was developed according to the JSR-223 specs, but has not yet * |
| * been tested via the JSR-223 TCK. BSF can therefore not be considered * |
| * a compatible implementation of JSR-223. * |
| *----------------------------------------------------------------------* |
| |
| However, the implementation is believed to be complete. |
| |
| * BSF-3.x is not compatible with BSF-2.4 - the API is completely different. |
| * BSF-3.x can be deployed and used on Java 1.4+ - it does not require Java 1.6 |
| |
| What the jars contain |
| --------------------- |
| bsf-api.jar - javax.script package which implements JSR-223 for Java 1.4+ |
| bsf-utils.jar - additional utilities for use with all JSR-223 implementations. |
| bsf-engines.jar - collection of 3rd party JSR-223 factory implementations |
| bsf-all.jar - all the above |
| |
| Incomplete packages |
| ------------------- |
| The org.apache.bsf.utils.http and org.apache.bsf.xml packages in bsf-utils.jar contain several classes. |
| These are not complete, and should not be relied on. |
| They are not needed in order to use the javax.script API. |
| |
| Changes from previous releases |
| ------------------------------ |
| |
| This 3.1 release is a maintenance release update to fix a few bugs. |
| |
| Compared with 3.0, the 3.1 release fixes the following: |
| * BSF-30 ScriptEngineManager no longer catches ThreadDeath |
| * BSF-29 ScriptException constructed via chained constructor |
| ScriptException(Exception) always returns String "null" for getMessage() |
| * Prevent Maven deploy from uploading test modules |
| |
| There are also a few improvements: |
| |
| * Test suite changes: renamed duplicate classes, better support for testing on Java 1.6/1.7 |
| * Added java-1.4/5/6/7 Maven profiles to allow cross-compilation and testing |
| * Use Jexl2 rather than Jexl-1 for testing |
| * removed duplicated test cases (jython-2.2) |
| |
| ---- |
| |
| Compared with 3.0-beta3, the 3.0 release fixes the following: |
| * updated test application. |
| * BSF-35 Wrong parameter type for [Simple]Bindings.put - key must be a String, not an Object |
| * Test run detects Java version and skips tests that don't apply to Java 1.4 |
| * Added JEXL test. |
| * Tidied build process to delete temporary directories |
| |
| The classes in the javax.script package have been overhauled to align the API, Javadoc and |
| the behaviour with the JSR-223 spec, and several unit tests have been added. |
| |
| Some of these changes may cause problems for programs that have been written to the BSF 3.0 |
| Javadoc rather than the JSR-223 spec. |
