Take a look at https://issues.apache.org/jira/browse/WICKET-4019 version 1.5.1.3, maybe it helps.

Check out version 5.2.1.2 - https://issues.apache.org/jira/browse/WICKET-4019, maybe it helps.
> Whole response is cached in memory
> ----------------------------------
>
> Key: WICKET-4113
> URL: https://issues.apache.org/jira/browse/WICKET-4113
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.18
> Reporter: Adam Pierzchała
> Priority: Critical
>
> In class {{org.apache.wicket.protocol.http.portlet.WicketResponseState}} there is used {{CharArrayWriterBuffer}} and {{ByteArrayOutputStream}} to cache in memory whole response.
> This creates issues with Java heap space when downloading big files:
> {noformat}
> Caused by: java.lang.OutOfMemoryError: Java heap space
> at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:70)
> at org.apache.wicket.protocol.http.portlet.WicketResponseState$1.write(WicketResponseState.java:439)
> at java.io.OutputStream.write(OutputStream.java:99)
> {noformat}
> I think there should be used stream implementation that caches big data amounts on disk e.g. {{org.apache.cxf.io.CachedOutputStream}}
