7.3.2.GA
The default stack-size for java is 512k , 1M on 64bit. With a simple jsp test, it looks like 150000-200000 bytes of stack would be required at least.
It appears some Java 8 ignores a request to set stack-size=32 bytes but some Java 11 honor the request resulting in java.lang.StackOverflowError. The actual call could potentially be different that ends with java.lang.StackOverflowError.
