Platform restriction: a parameter list's length cannot exceed 254

7e675caf-7289-4f20-83af-d221c3973ab3

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.

The obvious question is why you would even want that many parameters for a method.

It is NOT a bug - it is defined in the JVM spec to be a limit of 255.

See page 166

(The parameters_count item is one byte because a method descriptor is limited to 255 parameters.)
