OK, so scan the data for the object stream header sequence, which I believe is 0xCAFEBABE, but you will find it specified in the Protocol chapter of the Object Serialization Specification. You should have taken a hex dump, and posted it here, not the gibberish.

I figured out how to deserialize the object. After some research I went through the hex dump step by step to extract relevant information. The tricky part is that some of the data is sent in different packets over HTTP so the deserialization is kind of stitched together. Anyway here is what I was able to come up with. If anyone has any input on the unknown parts of the snippet below, please, do not hesitate to comment and I will attempt to edit my answer accordingly.
0005 – STREAM_VERSION
0a - UNKNOWN
73 – TC_OBJECT
72 – TC_CLASSDESC
0015 – length of the class name
616461732e746f6f6c6b69742e646174612e504144 - class name
efbfbd221844efbf – SerialVersionUID
bdefbfbdefbfbdefbfbd - UNKNOWN
02 - OBJECT SERIALIZABLE
0004 - NUMBER OF PROPERTIES (4)
44 - PROPERTY CODE (D : Double)
0001 - PROPERTY NAME LENGTH
61 - PROPERTY NAME (a)?
44 - PROPERTY CODE (D : Double)
0001 - PROPERTY NAME LENGTH
64 - PROPERTY NAME (d)
44 - PROPERTY CODE (D : Double)
0001 - PROPERTY NAME LENGTH
70 - PROPERTY NAME (p)
44 - PROPERTY CODE (D : Double)
0008 - PROPERTY NAME LENGTH

I figured out how to deserialize the object. After some research I went through the hex dump step by step to extract relevant information. The tricky part is that some of the data is sent in different packets over HTTP so the deserialization is kind of stitched together. Anyway here is what I was able to come up with. If anyone has any input on the unknown parts of the snippet below, please, do not hesitate to comment and I will attempt to edit my answer accordingly.
0005 – STREAM_VERSION
0a - UNKNOWN
73 – TC_OBJECT
72 – TC_CLASSDESC
0015 – length of the class name

Just to verify: Is what you want to show in your post actually mostly unprintable non-alpha-num noise? The problem is that what you see might be different from what I/we see, because of charactersets, unicode, ... I recommend to state that what you want to show is mostly unreadable. I realise that your question might be exactly about this, but a simple explanation/statement probably helps with the clarity. (downvote not by me, I only want to help)

See java.io.StreamCorruptedException: invalid stream header: 75720002. Also, please show us your code.

0x303061is two ASCII spaces followed by a lowercasea.Stringis not a container for binary data. Why don't you know where the Serialization starts and ends? How was this data produced?– user207421

OK, so scan the data for the object stream header sequence, which I believe is 0xCAFEBABE, but you will find it specified in the Protocol chapter of the Object Serialization Specification. You should have taken a hex dump, and posted it here, not the gibberish.
