There are a ton of exceptions shown in the log, but the one near
the end caught my eye:

Error: sun.jvm.hotspot.utilities.AssertionFailure: Corrupted constant pool: 108 ConstantTag:1

at jdk.hotspot.agent/sun.jvm.hotspot.oops.ConstantPool.getSignatureRefIndexAt(ConstantPool.java:391)

I'm not sure if that's the root cause of the failures or
if the root cause is hidden by the elided log output, but
it does look "interesting".
