I can't get to trac to create a ticket myself (some infinite redirect to the prefs page), please someone take care of this / open a ticket:
case class Copy(os:java.io.OutputStream) { def <<(source: javax.xml.transform.Source):Copy = { println("copy source") val buff = new Array[Byte](2048) source match { // case ss:javax.xml.transform.stream.StreamSource => case ss:{def getInputStream:java.io.InputStream} => println("is copy") var read=0 val is = ss.getInputStream println("starting read/write") while({read=is.read(buff); read>0}) { println("copy "+read) os.write(buff,0,read) println("written copy") } println("starting close") is close println("end copy") } this } def <<! { println("close copy") os.close } } Crashes the compiler at least since the nightly since July 5th - 2.7.1-final compiles it, but I get a runtime error later (can't access public method). The plugin warns the line below the commented correction: refinement AnyRef{def getInputStream: java.io.InputStream} in type pattern is unchecked since it is eliminated by erasure cheers, Carsten ---------- Forwarded message ---------- From: Carsten Saager <csaager@...> Date: Thu, Jul 17, 2008 at 12:39 AM Subject: Plugin 0617 An internal error occurred during: "Building workspace". To: scala-tools <scala-tools@...> I tried to recompile a project that compiled fine with an older version of plugin/scala compiler.

A small project with 1 file compiles fines, another one with 3 files compiles on the second clean build. Carsten |

This seems like a common crash in the current compiler, is there already an open ticket on this?

[scala] Reminder: Scala code dojo tomorrow evening in London

Dear All,
Just a quick reminder that the London Scala Users Group will be holding a code dojo tomorrow evening starting at 7. Thanks to Robert Rees at ThoughtWorks, we will have an excellent venue in Holborn. Jamie Webb, whom you will know from this mailing list is one of the most proficient Scala coders out there, will be giving an introductory talk on the language, after which we'll get our hands dirty with some code and some pizza. Full details are here: http://upcoming.yahoo.com/event/812966/ Hope to see you all there. Aaron |
