Unexpected exception in Play with Scala - scala

Question

I am having an Unexpected exception in my Play2 application with Scala. The same error as mentioned in this question
This is what I get in a browser:
scala.MatchError: java.lang.StackOverflowError (of class
java.lang.StackOverflowError)
play.PlayReload$$anonfun$taskFailureHandler$1.apply(PlayReload.scala:44)
play.PlayReload$$anonfun$taskFailureHandler$1.apply(PlayReload.scala:44)
scala.Option.map(Option.scala:145)
play.PlayReload$.taskFailureHandler(PlayReload.scala:44)
play.PlayReload$.compileFailure(PlayReload.scala:40)
play.PlayReload$$anonfun$compile$1.apply(PlayReload.scala:17)
play.PlayReload$$anonfun$compile$1.apply(PlayReload.scala:17)
scala.util.Either$LeftProjection.map(Either.scala:377)
play.PlayReload$.compile(PlayReload.scala:17)
My stack traces are very large. A part of them looks as follows:

I have tried the answers to change the heap and stack size but when I run jconsole it showed that it did not work.
I also tried to change its heap size from this link but it also did not work and I am still getting the same error.
Here is my build.sbt file :
name := """myproject"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayScala)
scalaVersion := "2.11.1"
fork in run := true
javaOptions in run ++= Seq(
"-Xms1G", "-Xmx2G", "-XX:MaxPermSize=1024M", "-XX:+UseConcMarkSweepGC")
//SBT_OPTS=-Xss8m
//JAVA_OPTS="-Xms512m "
//val buildSettings = Defaults.defaultSettings ++ Seq( javaOptions += "-Xms1G -Xmx2G"
//)
libraryDependencies ++= Seq("org.scalatest" %% "scalatest" % "2.2.1" % "test"withSources() withJavadoc(),
"com.esotericsoftware.kryo" % "kryo" % "2.10",
"org.mongodb" %% "casbah" % "2.8.0",
"org.slf4j" % "slf4j-api" % "1.6.4",

"ch.qos.logback" % "logback-core" % "1.0.9",
"ch.qos.logback" % "logback-classic" % "1.0.9"
)
Please guide me.

Answer 1

Changing the stack size worked for me
I used this command to run the project
activator run -J-Xss4M -server
