I am using the Standard (non-Scala) debugger due to another issue. I set a Java breakpoint on when RuntimeException is thrown, and I get an "Editor could not be initialized" error when the breakpoint is hit (in
). The stack trace is:
scala.sys.package$.error(java.lang.String) line:27
). The stack trace is:

This is an error in the Java debugger, I'm not sure if this can be fixed on the Scala IDE side, without moving to the Scala debugger.
Test case:
Works fine on Scala IDE 3.0.1 for Eclipse Indigo (3.7.2)
Doesn't work on Scala IDE 3.0.1 for Eclipse Juno/Kepler (4.3.1)
Doesn't work on Scala IDE 3.0.2 for Eclipse Juno/Kepler (4.3.1)
This problem has no relation with which debugger is used. If it fails, it fails with both.
It looks like a problem with the JDT aspects. It is likely due to a slight change in the internals of JDT between 3.x and 4.x.
// add breakpoint on scala.sys.package$, line 27
object ScalaMain {
def main(args: Array[String]) {
sys.error("Test")
}
}
