How to extract public key from a .der file in SubjectPublicKeyInfo format

I have a public key that appears to be in the SubjectPublicKeyInfo format. I say "appears" because the only thing I know about this key that it loads a Java application using X509EncodedKeySpec which, according to documentation is used for loading keys in SubjectPublicKeyInfo format.

I've been unable to parse the file with openssl with either pkcs8, x509 or asn1parse.

Below is the result of asn1 parse:

openssl asn1parse -in public_key.der -inform der

0:d=0  hl=4 l= 290 cons: SEQUENCE          
4:d=1  hl=2 l=  13 cons: SEQUENCE          
6:d=2  hl=2 l=   9 prim: OBJECT            :rsaEncryption
17:d=2  hl=2 l=   0 prim: NULL              
19:d=1  hl=4 l= 271 prim: BIT STRING        

Based on that output I've tried extracting the actual key by experimenting with different offsets and lengths then saving it to the .der file:

openssl asn1parse -in public_key.der -inform der -offset <> -length <l> -out public_key.der

Then I'd feed the output back to openssl:

openssl pkcs8 -inform DER -nocrypt -in public_key.der

But keep getting the same error:

Error decrypting key 140436029183664:error:0D0680A8:asn1 encoding

Update: output of
