Cause and fix for EvaluatorException (Explicitly calling java overloaded methods from javascript)

Question

How can I resolve this type of error?

Caused by: sun.org.mozilla.javascript.internal.EvaluatorException: The choice of Java constructor write matching JavaScript argument types ([B) is ambiguous; candidate constructors are:
void write(int)
void write(byte[]) (<Unknown Source>#28)

Answer 1

This exception may be thrown for other reasons but, in the case above, it is a problem with calling an overloaded method.

I came across this error trying to write to a FileOutputStream like:

out.write(binaryData);

to fix it I changed it to:

out["write(byte[])"](binaryData);

In short the bracket notation explicitly calls the appropriate method.
