Vineflower version

1.10.0

Describe the bug

While decompiling the gdx jar version 1.9.11 (https://repo1.maven.org/maven2/com/badlogicgames/gdx/gdx/1.9.11/gdx-1.9.11.jar), Vineflower will deadlock itself. When using --thread-count=1 the log suggest that the decompiler hangs while processing com/badlogic/gdx/utils/OrderedMap.
