The Eclipse JDT compiler appears to have a problem whereby, under certain circumstances, Java 8 lamdas are not deserializing correctly and instead throw an IllegalArgumentException. I'm using the most recently distributed maintenance build, as follows:
Eclipse SDK
Version: Luna SR2 (4.4.2)
Build id: M20141210-0900
There are existing bugs / SO entries that report similar issues that have been (at least partially) resolved in Luna SR2 (4.4.2) M20141210-0900. I have personally verified that the following issues have been resolved.
Java 8 lambdas that access instance fields and methods can't be deserialized
https://bugs.eclipse.org/bugs/show_bug.cgi?id=449453
https://bugs.eclipse.org/bugs/show_bug.cgi?id=439889
To give some context to my problem, I'm using Apache Wicket which calls for the use of anonymous inner classes quite frequently. Since upgrading to Java 8, I've started re-factoring the anonymous inner classes into lamda expressions, which really helps reduce boiler plate code.
Apache Wicket uses serialization to cache web pages that the user has visited, deserializing the pages when the uses navigates back to a previous page. Whilst my code is serializing quite happily, it will not deserialize. The posts linked above led me to focus my investigation; it transpires that compiling under javac resolves the issue. This demonstrates that this is another JDT compiler bug. It isn't however fixed alongside the other lamda deserialization bugs in the latest maintenance release.
There are several areas from which I could benefit from a response:
Is there anything obvious that I could be doing wrong that would lead to a successful serialization but unsuccessful deserialization?
Is there an outstanding JDT compiler bug for this that I've missed?
I'm finding debugging this one really tricky. Because the classes I'm having to debug aren't compiled for debug, all I can inspect is the stack, which I find very limiting. Without being able to reproduce the problem outside of some fairly lengthy Wicket code, I can't really raise a helpful bug. Does anyone have any tips for debugging core libraries?
Has anyone had any success using different serialization libraries with Wicket? At a glance it appears that Kryo Serializer isn't battle tested.
Ideally this is a known bug, or with some assistance I can get to the bottom of what's causing this and reproduce the problem in the form of a small example and raise a meaningful bug. However, if there are any workarounds that spring to mind, I'd be keen to hear those too. Thanks in advance.
