For each type it loads, a Java Virtual Machine must store aconstant pool. A constant pool is an ordered set of constants used by the type, including literals (string, integer, and floating point constants) and symbolic references to types, fields, and methods. Entries in the constant pool ...
Java Virtual Machine instructions do not rely on the run-time layout of classes, interfaces, class instances, or arrays. Instead, instructions refer to symbolic information in theconstant_pooltable. Allconstant_pooltable entries have the following general format: cp_info { u1 tag; u1 info[]; }...
“invalid byte tag in constant pool”是一个在Java虚拟机(JVM)加载类文件时可能遇到的错误。它表明在类文件的常量池中遇到了一个无效的字节标签(byte tag)。常量池是类文件中用于存储各种常量(如字符串、整数、浮点数、类引用等)的区域,而字节标签则用于标识这些常量的类型。 2. 可能原因 类文件损坏:类文件在...
The constant pool plays an important role in the dynamic linking of Java programs. In addition to literal constant values, the constant pool contains the following kinds of symbolic references: 在动态链接的Java程序中,常量池充当了十分重要的角色。除了字面常量(或者说直接量)值以外,常量池还可以容纳下面...
The String constant pool uses aHashmapin its implementation. Each bucket of theHashmapcontains a list ofStrings with the same hash code. In earlier versions of Java, the storage area for the pool was a fixed size and could often lead to the“Could not reserve enough space for object heap...
