While doing DiamondDagger590/McRPG#194 I ran into this issue.
ArrayStoreExceptionwhen using PlaceholderAPI with GUI itemsWhen a player with PlaceholderAPI installed opens a GUI (e.g.,
/mcrpg), anArrayStoreExceptionis thrown:java.lang.ArrayStoreException: net.kyori.adventure.text.minimessage.tag.resolver.TagResolver$1 at BaseItemBuilder.getPlaceHolders(BaseItemBuilder.java:1115)Cause
In
getPlaceHolders(), the array is declared asTagResolver.Single[]butCorePapiHook.getTagResolver()returns aTagResolver(notTagResolver.Single). Java arrays are covariant but enforce runtime type checking, causing the store to fail.Fix
Change the array instantiation from
new TagResolver.Single[...]tonew TagResolver[...]. BothTagResolver.SingleandTagResolvercan be stored in aTagResolver[]array.
