- Line 6918: Update the readGroupsEnabled guard in AbstractUserStoreManager’s
paginated role methods to reject access when either the caller or the resolved
userStoreManager has group reading disabled. Preserve the existing caller-level
check and add the resolved-store flag check before listing or counting roles.

- Around line 75-86: Update JDBCRealmUtil.getSQL so MSSQL, DB2, Oracle, and H2
list defaults are inserted only when the base list SQL still matches the shipped
value, and insert the H2 count default only when the base count SQL matches its
shipped value, using the whitespace-insensitive comparison from
validatePaginatedRoleSQL. Update the H2 list and count selectors to fall back to
their respective base properties when no H2-specific property is configured;
preserve explicitly configured dialect-specific properties. Do not add MSSQL,
DB2, or Oracle count handling.

- Around line 938-939: Update the query selection in the method containing
`GET_ROLE_FILTER_PAGINATED` to prefer an explicitly customized type-specific
query, then a customized base paginated query, before falling back to the
shipped type-specific default. Apply the same precedence to the H2 branch so
custom-schema stores use their configured base query.
- Around line 947-948: Update the count-query key selection so non-H2 databases
use the configured type-specific key,
JDBCRealmConstants.GET_ROLE_FILTER_PAGINATED_COUNT + "-" + type, when present
and otherwise fall back to JDBCRealmConstants.GET_ROLE_FILTER_PAGINATED_COUNT.
Preserve the existing H2-specific key behavior.

Purpose
Resolves wso2/product-is#28294 (user store part).
A JDBC user store lists its roles through
doGetRoleNames(filter, maxItemLimit), which appliesMaxRoleNameListLength(100 by default) throughsetPSRestrictionsand has no offset. A caller that needs the groups of a store holding more than 100 groups, such asGET /scim2/Groups?domain=PRIMARY, gets the first 100, sees a total of 100, and gets nothing forstartIndex=101. It can neither page past the limit nor learn the real number of groups.Goals
Let a caller read one window of a user store's role names, ordered by name, and count the names matching the same filter.
Approach
AbstractUserStoreManagergets publiclistRoleNames(filter, limit, offset)andcountRoleNames(filter)for a domain qualified filter (PRIMARY/*,SECONDARY/grp*). They delegate to new protected hooksdoGetRoleNames(filter, limit, offset)anddoCountRoleNames(filter). As in the paginated user listing, the offset is a one based start index (a value below 1 means the first page) and a limit below 0 or aboveMaxRoleNameListLengthis reset to that maximum. The two methods run outsidecallSecureon purpose: that wrapper rethrows onlyUserStoreException, so it would turn theNotImplementedExceptiondecline into a failure instead of a fallback; the newerlistGroups(Condition, ...)API takes the same approach.NotImplementedException. So do a filter without a domain, theInternal,ApplicationandWorkflowdomains, a store that is not anAbstractUserStoreManager, and a manager with group reading disabled. A caller treats that as "use the existing listing". An unknown domain is aUserStoreClientException.JDBCUserStoreManagerimplements both hooks with a windowed query ordered byUM_ROLE_NAMEand a matchingCOUNT, per database type, following the paginated user listing:RoleFilterPaginatedSQL(with-mssql,-db2and-oraclevariants and an H2 form) andRoleFilterPaginatedCountSQL(with an H2 form).MaxSearchTimeapplies.JDBCRealmUtilseeds the statements like the other SQL properties, and a user store can set its own.GetRoleListSQL,GetRoleListSQLH2or their escape variants) that differs from the shipped statement, or a subclass that overridesdoGetRoleNames(filter, maxItemLimit)in Java. Such a store keeps today's listing instead of running the default query againstUM_ROLE, and the decline is logged once per store at WARN, naming the statement properties that database type reads (for exampleRoleFilterPaginatedSQL-mssql, orRoleFilterPaginatedSQLH2andRoleFilterPaginatedCountSQLH2on H2). Configured SQL is compared with whitespace collapsed. A store that wants to page with its own schema sets those properties; the placeholders are documented on the shipped statements (name pattern, tenant id, then the window: row count and rows to skip by default and on H2, first and last row number on SQL Server and DB2, last row number and rows to skip on Oracle).RoleFilterPaginatedSQL-<type>for it. The database type is detected once per store, so a store that declines does so before borrowing a connection on later calls.MaxSearchTimefails the request rather than returning an empty page as the existing listing does, so a truncated page is not mistaken for a complete one; the error names the timeout and is logged.getRoleNamesanddoGetRoleNames(filter, maxItemLimit)are unchanged.Developer Checklist (Mandatory)
