Jahia Cloud - Threads and heap dumps provider group_work

Bug Fixes

Fix RepositoryException: Invalid path for dump folders with colons in their name (SUPPORT-608)

Dump directories generated by Jahia Cloud use ISO 8601 timestamps as folder names
(e.g. 2026-01-22T14:15:28.106Z_cluster_restart). The colon character (:) in those
names is the JCR namespace separator and is illegal in unqualified JCR node names,
causing Jackrabbit to throw a MalformedPathException whenever the external content
store provider tried to look up extension nodes for those folders:

javax.jcr.RepositoryException: Invalid path: … ':' not valid name character
    at org.jahia.modules.external.ExternalNodeImpl.getExtensionNode(…)

Root cause: JCRContentUtils.escapeLocalNodeName() (Jackrabbit's
Text.escapeIllegalJcrChars) escapes % as %25. Because VFS2 returns file paths
in percent-encoded URI form, a file named …T08:44:34… was already represented as
…T08%3A44%3A34… by the time the escape function was applied — causing % to be
re-encoded to %25 (double-encoding), which then confounded extension-node path
resolution under Jahia 8.2.3.0.

Fix: Introduced a package-private Escaping utility class whose
escapeIllegalJcrChars method encodes only the characters that are genuinely illegal
in JCR unqualified names ([ ] * | :), deliberately leaving % untouched. This
prevents double-encoding of paths that VFS2 has already percent-encoded. VFS2's
resolveFile() uses URI semantics and decodes %3A back to : transparently when
accessing the local filesystem, so path resolution is correct regardless of whether
the input carries a bare colon or an encoded one.

Improvements

Privilege check migrated to JCRSessionFactory (SUPPORT-608)

The admin-access check in JahiaCloudDumpDataSource.getPrivilegesNames() was
rewritten to use JCRSessionFactory.getInstance().getCurrentUserSession() +
hasPermission("admin") instead of the deprecated
ServicesRegistry → JahiaGroupManagerService.isAdminMember() call.

• Open the repository explorer and go the mount point
• Only users member of the systemsite group site-administrators will be able to access the mount point

• Download the jar and deploy it on your instance
• Go to Administrat -> Server settings -> System components -> Mount points
• Add a new mount point of the type Jahia Cloud - Threads and heap dumps mount point
  • Give a name to the mount point
  • Specify where to mount it
