I am getting the above mentioned Error from Scala compiler.
I am quite new to Scala and experimenting with it by converting a Java project that I have, to Scala. In my Java project, I am using Apache 'commons-chain' and I have a class that is extending 'org.apache.commons.chain.impl.ContextBase' and I am getting this error for it. I searched the internet it seems this problem has something to do with type erasure but my class doesn't not do anything special, just inherits from this class.
class SpecialContext extends ContextBase {
}
and here is the exact error I get..
Error:(10, 7) illegal inheritance;
class SpecialContext inherits different type instances of trait Map:
java.util.Map[K,V] and java.util.Map[K,V]
class SpecialContext extends ContextBase {
One of the attractions of Scala for me, while I can use nice language features of Scala, I would be still able to use the extensive number of open source libraries of the Java. After this experience, I am questioning this fact, considering my class not doing anything special, is it always this problematic to integrate the Java world and Scala world.
First my question is off-course is there a solution for the problem I described above?
Second question is, how is your experience integrating Scala and Java libraries? Or am I following the wrong way, are there ports of the popular Java libraries to Scala, like command-chain here, or lets say Spring....
Thx for answers.
