cxhttt233 opened a new issue, #8249: URL: https://github.com/apache/hop/issues/8249
### Apache Hop version? 2.20.0-SNAPSHOT-20260903 ### Java version? 21 ### Operating system Docker ### What happened? This error was encountered during normal Hop Web use. The code analysis below was assisted by Codex and the suspected cause still needs confirmation. When expanding folders or using Expand All in the Explorer, the server log repeatedly shows: ERROR: Error creating composite icon: A factory-created resource cannot be disposed. java.lang.IllegalStateException: A factory-created resource cannot be disposed. Typical call path: ExplorerPerspective.callPaintListeners ExplorerPerspective.addExplorerTreeChild ExplorerPerspective.refreshFolder ExplorerPerspective.expandAll Current "LintStatusFilePainter" contains the comment: // No composite (Hop Web cannot draw one) but immediately afterwards still calls "getOrCreateComposite()", which creates an SWT "Image" and "GC". This appears to still enter an off-screen composite image path that RAP/Hop Web cannot handle. Reproduction: Explorer → expand a folder containing many Hop files / Expand All. Observed on "apache/hop-web:2.20.0-SNAPSHOT-20260903", Java 21, Docker/Linux ARM64.
