Out of bounds for length 0

[ctwinovalon]

Ran --server xyz --contract file.json

Ran for a while on various endpoints and died on one of them with:

java.lang.StringIndexOutOfBoundsException: Range [-1, 0) out of bounds for length 0
...
com.endava.cats.generator.simple.StringGenerator.generateExactLength(StringGenerator.java:127)

Looks like this section:

cats/src/main/java/com/endava/cats/generator/simple/StringGenerator.java

Lines 125 to 132 in 44fb351

	if (initialValue.length() != length) {
	int startingAt = initialValue.length() - 1;
	String toRepeat = initialValue.substring(startingAt);
	initialValue.append(toRepeat);
	while (initialValue.length() < length) {
	initialValue.append(toRepeat);
	}
	}

The test if (initialValue.length() != length) { should be if (initialValue.length() > 0 && initialValue.length() != length) {
