ghidra: Loading 'Defined Strings' (after successful analysis) hangs and slows down UI

Describe the bug Loading ‘Defined Strings’ (after successful analysis) hangs. It is a fairly large binary with around ~600000 strings. Status bar is getting stuck at 37% (in my case after waiting 15 minutes), 100% cpu is consumed on one thread/core.

The sand glass is still animated but the whole UI froze.

Memory exhaustion is not the cause (3 GB from 8GB jvm heap consumed).

Expected behavior Defined strings view should neither hang nor block ghidra

Environment (please complete the following information):

• OS: [e.g. macOS 10.14.2] Windows 10
• Java Version: [e.g. 11.0] OpenJDK 11.0.2
• Ghidra Version: [e.g. 9.1.2] 9.2.3
• Ghidra Origin: [e.g. official ghidra-sre.org distro, third party distro, locally built] official
