Turns out the fears about infinities are basically unfounded - it appears the CssParser does not like scientific notation, and I could not get it to trip with a very small decimal step. Example: transition-timing-function: linear(0, 1.4E-45, 0.063, 0.25, 0.563, 1 36.4%, 0.812, 0.75, 0.813, 1 72.7%, 0.953, 0.938, 0.953, 1 90.9%, 0.984, 1 100% 100%); bails out with Unexpected token '1.4E' at [7,40] Nov 25, 2025 7:47:46 AM javafx.css.CssParser reportException WARNING: Please report java.lang.NullPointerException at: javafx.graphics/javafx.css.CssParser.term(CssParser.java:5127) javafx.graphics/javafx.css.CssParser.expr(CssParser.java:5021) modules/javafx.graphics/src/main/java/javafx/animation/Interpolator.java line 98: > 96: > 97: /** > 98: * Returns a piecewise-linear interpolator with the specified control > points. Question: do we need to specify that a new instance is returned each time (as opposed to some sort of caching as with `Integer.valueOf`)? ------------- Marked as reviewed by angorya (Reviewer).
