Frequent crashes on macOS 15 while editing Java files in WebCore::BackForwardCache::markPagesForContentsSizeChanged #3140
Description
Since updating to Eclipse IDE 2026-03 I am experiencing crashes frequently, but somewhat randomly, while editing Java files. The crash reporter shows this stack trace:
