I get this error compiling some Scala code based on the Java 8 jdk. It looks like the JVM has a restriction of no more that 254 parameters on a method which is the root cause of this error message. I've not been able to find much on this error. Is the 254 parameter limit treated as an issue that is being fixed in a late Java release or has it already been addressed in a more recent version. I've got the 1.8.0_151 version installed.
