## GWT 2.8.2 erschienen

07.11.2017 · [Christian Ullenboom](https://tutego.de/blog/javainsel/author/admin/)

##### [http://www.gwtproject.org/release-notes.html#Release\_Notes\_2\_8\_2](http://www.gwtproject.org/release-notes.html#Release_Notes_2_8_2 "http://www.gwtproject.org/release-notes.html#Release_Notes_2_8_2")

##### Highlights

- Supports running in Java 9. Note that this does not yet mean that GWT can compile Java 9 sources, or support the Java 9 JRE changes, but that a Java 9 JRE can be used to compile a GWT project. Do note that the new `--module-path` flag is not supported, but`-classpath` must still be used as in the past.
- Chrome 61 removed functionality that had been used for reading the absolute top/left values. The internal implementation has been updated to reflect modern standards.
- Uncaught exception handler will now receive all errors on the page, as handled by`window.onerror`. This may potentially be a breaking change if there were misbehaving scripts on the page. To disable this functionality, set the property`gwt.uncaughtexceptionhandler.windowonerror` to `IGNORE`:

```text

```

For more details, see `com.google.gwt.core.Core`.

##### Bug fixes

- LookupMethodCreator creates too large method
- NativeRegExp should use iframe instance, fixing Edge JIT bug
- JsProperty getter/setter sometimes were reported as incompatible
- Instantiating native JsTypes from JSNI results in `InternalCompilerException`
- Remove the SUBSIZED characteristic from filtered streams
- Internal compiler exception when using native JsType varargs in a JsMethod
- Regression in `String`.`toLowerCase` and `toUpperCase` for some locales, specifically for Turkish
- Missing bounds check in `String`.`charAt`
- Fix AIOOBE when compiling method references involving varargs.
- Apply HtmlUnit workaround ensuring that window.onerror is called correctly

##### Miscellanous

- Migrated lang/jre emulation JSNI to JsInterop to share with J2CL
- Added ErrorProne to gwt builds
- Improved compliance with CSP
- Added emulation for `java.io.Externalizable`
- Added emulation for `java.lang.reflect.Array`
- JSO.equals/hashcode will delegate to the JS object if it has methods with those names
- Removed outdated or unused parts of project
- Migrate guava JRE emulation to GWT
- HtmlUnit tests are now run in batch mode
