Code Review

This pull request significantly expands OpenCypher function support, adding geospatial, temporal, vector, and string functions along with GQL-conformant aliases. It also improves test parallelization by updating the TestHelper and implementing resource locks across the test suite. Feedback focuses on fixing a potential NumberFormatException for empty vector strings, ensuring split() preserves trailing empty strings per Cypher specifications, restoring robustness in point() coordinate parsing, and handling potential nulls or incorrect types in map-based distance calculations.

The current parsing logic will throw a NumberFormatException if the input string represents an empty array []. When inner is an empty string, split(",") returns an array containing one empty string, which Float.parseFloat() cannot handle. Additionally, it doesn't handle cases with extra commas or whitespace between values gracefully.

Suggested change

	final String inner = trimmed.startsWith("[") && trimmed.endsWith("]") ? trimmed.substring(1, trimmed.length() - 1) : trimmed;
	final String[] parts = inner.split(",");
	final float[] result = new float[parts.length];
	final String inner = trimmed.startsWith("[") && trimmed.endsWith("]") ? trimmed.substring(1, trimmed.length() - 1).trim() : trimmed;
	if (inner.isEmpty())
	return new float[0];
	final String[] parts = inner.split(",");
	final float[] result = new float[parts.length];

Java's String.split(regex) discards trailing empty strings by default. To comply with the Cypher specification, which expects trailing empty strings to be preserved (e.g., split('a,b,', ',') should return ['a', 'b', '']), you should use the two-argument version of split with a negative limit.

Suggested change

	return List.of(str.split(Pattern.quote(delimiter)));
	return List.of(str.split(Pattern.quote(delimiter), -1));

This change reduces robustness compared to the previous implementation. The previous code used GeoUtils.getDoubleValue(), which safely handles both Number and String inputs. The direct cast to Number will throw a ClassCastException if the input is a string representation of a coordinate.

Suggested change

	final double lat = ((Number) args[0]).doubleValue();
	final double lon = ((Number) args[1]).doubleValue();
	final double lat = com.arcadedb.function.sql.geo.GeoUtils.getDoubleValue(args[0]);
	final double lon = com.arcadedb.function.sql.geo.GeoUtils.getDoubleValue(args[1]);

[gemini-code-assist]

This code is unsafe as it assumes the map values are non-null and of type Number. If a coordinate is null in the map (which is possible in Cypher), this will throw a NullPointerException. If it's a String, it will throw a ClassCastException. It is safer to use GeoUtils.getDoubleValue() after verifying the values are not null.
