I'm attaching the jstack for the daemon and it seems like having troubles while relocating:
Daemon worker" #19 prio=5 os_prio=31 tid=0x00007fbebc185800 nid=0x5c03 runnable [0x0000700003512000]

at com.github.jengelman.gradle.plugins.shadow.impl.RelocatorRemapper.map(RelocatorRemapper.groovy:101)
The interesting part is that we don't see this happening with projects consuming Shadow plugin 5.2.0. So wondering if this is something particular in the setup for this build
