invalid double value: "%s"

Error message

invalid double value: "%s"

What it means

Thrown by IntegerValue.parseValue when the string supplied for an integer-valued option cannot be parsed by Integer.valueOf. It is wrapped in InvalidArgumentException so the option framework can report which option name failed. Note the message text says 'invalid double value' even though the value is parsed as an int — a copy-paste wording bug in the source.

Solutions

1. Correct the value to be a valid base-10 int (no decimal point, no whitespace): e.g. pass 3 instead of 3.5
2. If a fractional value is intended, use the double-based option type instead of IntegerValue
3. Trim/validate the string before it reaches the option parser (shell quoting, config files)
4. As a contributor, fix the misleading message in IntegerValue.java:48 to say 'invalid integer value'

Example fix

# before
-D:GraalCompileQueueSize=1.5   -> InvalidArgumentException: invalid double value: "1.5"

# after
-D:GraalCompileQueueSize=2

if (arg == null || !arg.matches("[+-]?\\d+")) {
    throw new InvalidArgumentException(name, "value must be a base-10 int, got: " + arg);
}

catch (InvalidArgumentException e) { report option name + raw value; do not retry with the same string }

When it happens

Trigger: Calling parseValue(arg) on an IntegerValue (e.g. via the args framework parsing a command line or test harness) with a string like "1.5", "abc", an empty string, or a value outside int range; NumberFormatException is caught and rethrown as InvalidArgumentException.

Common situations: Passing a floating-point number where an int option is expected (e.g. -D:SomeInt=3.5), trailing whitespace or quotes in the value, hex/underscores not supported by Integer.valueOf, or hitting the int overflow range on a value that looks valid.
