Re: [platform-swt-dev] Update SWT to Java 8

[Leo Ufimtsev <lufimtse@xxxxxxxxxx>]

Hello Szymon, 

I'm not aware of java 8 compilers as java is interpreted by a jvm (?), or I have not used a compiler for java. (Is there a compiler that you use on some platform?)

I used openJDK afaik.

I did as following:

- checked out commit: https://git.eclipse.org/r/#/c/75240

- Changed classpath to use the GTK version

- Now SWT can handle Java 8 code. (See example screen shot that uses lambda function).

- On my Fedora 24:

-- I tested SWT jUnit with Gtk3.20-Gtk3.10 and Gtk 2. 

-- I tested launching various snippets (ex Control example)

-- I tested child eclipse with SWT in java 8 mode.

Please let me know if you have further questions. 

Screenshot of SWT running a little bit of Java 8 code (lambda) in a child eclipse.

Hi Leo,

When you say "function well", did you test running SWT on Java 8 as-is or compiling SWT with the Java 8 compiler and then running on Java 8?
