I would do
public String getTypeForAlias(String alias) {
if (alias==null) return null; // this shall solve NPE on
alias.toLowerCase()
String type = TYPE_ALIASES.get(alias);
if (type != null) {
return type;
}
type = TYPE_ALIASES.get(alias.toLowerCase()) *// NPE STILL HERE*;
if (type == null) {
type = alias;
}
//populate for future use
TYPE_ALIASES.put(alias, type);
return type;
}

Hi Dave,
It still does not address the NPE issue. If an alias is NULL. What
should be the behavior?
public String getTypeForAlias(String alias) {
String type = TYPE_ALIASES.get(alias);
if (type != null) {
return type;
}
type = TYPE_ALIASES.get(alias.toLowerCase()) *// NPE STILL HERE*;
if (type == null) {
type = alias;
}
//populate for future use
TYPE_ALIASES.put(alias, type);
return type;
}
Thanks,

Hello,
I am getting an NPE exception in the JDBC driver 42.2.23.
When the alias is null, NPE results. Is it possible to handle
null value ? I have filled a bug against RCA
https://github.com/vladmihalcea/hibernate-types/issues/335
<https://github.com/vladmihalcea/hibernate-types/issues/335>.
But, I thought that PSQL Driver can handle it more gracefully.
