Flink Java 8 Lambdas will work again with future Eclipse compilers
Hi all,
as some of you may already know, Flink's Java 8 Lambdas currently only
worked if the job has been compiled with the Eclipse JDT 4.4 compiler
because this compiler saves important type information in the class files.
Unfortunately, this feature was not officially supported by the Eclipse
team, which is why it has been remove as part of another bugfix in
version 4.4.1.
After I had contact with the guys of the Eclipse JDT team, they created
a patch to re-introduce the functionality with a compiler option (see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=449063).
So we won't have problems with the Eclipse JDT compiler in future
releases :-)
I'm also working on a patch for the javac compiler. I will submit it
after I have finished my current task with the type hints.
Regards,
Timo
