### Search before asking - [x] I had searched in the [issues](https://github.com/apache/fury/issues) and found no similar issues. ### Version When deserializing a POJO type containing double fields using `FuryInputStream` with the initial buffer size < the serialized buffer size of a single record, the deserialized value is wrong. Increasing the initial buffer size resolves the issue. ### Component(s) Java ### Minimal reproduce step - POJO class to serialize ```java public class SimpleType { // Changing this to an int value won't produce wrong result public double dVal; public SimpleType() { dVal = 0.5; } } ``` - Test: ```java Fury fury = Fury.builder() .withLanguage(Language.JAVA) .build(); fury.register(SimpleType.class); SimpleType v = new SimpleType(); // Size: 12 System.out.println(fury.serialize(v).length); ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); fury.serialize(outputStream, v); InputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray()); // <11: wrong result // >= 12: correct result FuryInputStream input = new FuryInputStream(inputStream, 11); SimpleType vout = (SimpleType) fury.deserialize(input); // java.lang.AssertionError: // Expected :0.5 // Actual :1.8227805048890994E-304 Assert.assertEquals(v.dVal, vout.dVal, 0.001); ``` ### What did you expect to see? The deserialized value = 0.5. ### What did you see instead? The deserialized value = 1.8227805048890994E-304. ### Anything Else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
