Added

• Local AI via generic OpenAI-compatible provider (OpenAiLlmProvider) with auto-launch of llama-server
• Tool-calling system for AI: 8 tools (get_thread_stack_trace, search_stack_frames, get_lock_info, get_top_cpu_threads, compare_thread_across_dumps, get_dependency_tree, get_system_properties, get_raw_thread_dump_section)
• --no-tools flag, --think flag for showing LLM reasoning, --short for succinct summaries
• Retry with exponential backoff on transient HTTP errors (429, 502, 503)
• Robust <think> tag handling for streaming (handles tags split across chunks)
• TablePrinter utility for formatted table output

Changed

• Replaced Ollama provider with generic OpenAI-compatible provider; config keys are now local.host and local.llama-server-model
• --short mode no longer double-streams (full analysis is suppressed, only summary shown)

Removed

• OllamaLlmProvider and Ollama-specific config keys (ollama.host, ollama.think-mode)

Direct Download

Download from the assets below:

• jstall.jar - Executable JAR file (requires Java 21+)
• jstall - Standalone launcher script (Unix/Linux/macOS)
• jstall-minimal.jar - Minimal executable JAR (SapMachine only, see note below)
• jstall-minimal - Minimal launcher script (SapMachine only, see note below)

Important (jstall-minimal):
The jstall-minimal artifacts are intended to be used only in combination with a recent SapMachine release.
These artifacts don't come with asprof or libasyncprofiler binaries bundled, so you need to ensure that your Java installation includes them,
SapMachine does.

Usage:

# Using the script (recommended for Unix-like systems)
./jstall <pid>

# Using the JAR directly
java -jar jstall.jar <pid>

Added

• Live mode (--live): interactive TUI with async data collection, tab navigation, sorting, filtering, and scroll
• --color flag for colored output in live mode (thread states, CPU % intensity)
• Secondary sort in live mode: press s then 1-9 to add tiebreaker columns
• Interval adjustment (+/-) and force refresh (r) in live mode
• Collection/analysis timing display in live mode status bar
• Scroll position indicator in footer bar
• --top=<n> option for threads command to show only top N threads by CPU time (works with --live mode)

Changed

• CPU time formatting: values below 10ms now display as milliseconds (e.g., 3ms) instead of 0.00s

Fixed

• Comma-grouped numbers (e.g., 15,177) now sort correctly in tables
