Calls to GeoTools.init(...) or to Hints.putSystemDefault(...) are expected to
happen in user-code only. It should never happen anywhere in GeoTools library.
If the goal is to use Boolean.TRUE as the default value when the
USE_JAI_IMAGEREAD hint is not specified, then this handling should be performed
in the FormatFactorySpi constructor:
public FormatFactorySpi(Hints hints) {
boolean useJaiImageRead = true; // Default value
if (hints != null) {
Boolean hint = (Boolean) hints.get(Hints.USE_JAI_IMAGE_READ);
if (hint != null) {
useJaiImageRead = hint.booleanValue();
}
}
}
