Research direction

Start with the reported failure in org.eclipse.jdt.internal.core.index.DiskIndex.readCategoryTable at DiskIndex.java:681 and trace how IndexManager.saveIndexes reaches it. Reproduce the Java heap exhaustion if possible, then establish a concrete fix or mitigation that prevents the qualified index update from failing.
