This paper provides an in-depth exploration of the "JARs that were scanned but no TLDs were found in them" warning that occurs during Tomcat 9 startup. By analyzing the TLD scanning mechanism, it explains that this warning is not an error but an optimization hint from Tomcat to improve performance. Two main solutions are presented: adjusting log levels to ignore the warning, and enabling debug logging to identify JAR files without TLDs and add them to a skip list, thereby significantly enhancing startup speed and JSP compilation efficiency. Supplementary methods, including automated script-based JAR identification and flexible scanning configurations in Tomcat 9, are also discussed, offering comprehensive guidance for developers on performance optimization.

This article provides an in-depth exploration of rendering issues that may occur in WebKit/Blink browsers (such as Chrome and Safari) when dynamically modifying CSS styles via JavaScript. When updating element styles through methods like className modification, certain descendant elements may not immediately repaint, leading to visual inconsistencies. The article analyzes the root cause of this phenomenon—browser rendering engine optimizations may delay or skip unnecessary repaint operations. Based on best practices, we detail two effective solutions: forcing a redraw by temporarily modifying the display property and accessing offsetHeight, and using CSS transform: translateZ(0) to promote elements to composite layers. Both methods have their advantages and disadvantages, suitable for different scenarios. The article also explains how these solutions work from the perspective of the browser rendering pipeline and discusses future standardized approaches such as the CSS will-change property.
