Byte Code Engineering Library
The Byte Code Engineering Library is intended to give users a
convenient way to analyze, create, and manipulate (binary) Java class
files (those ending with .class). Classes are represented by objects
that contain all the symbolic information of the given class: methods,
fields, and byte code instructions, in particular.
Such objects can be read from an existing file, transformed by a
program (such as a class loader at runtime), and dumped to a file
again. An even more interesting application is the creation of classes
from scratch at runtime. The Byte Code Engineering Library (BCEL) may
also be useful if you want to learn about the Java Virtual Machine
(JVM) and the format of Java .class files.
BCEL is already being used successfully in several projects, such as
compilers, optimizers, obfuscators, code generators, and analysis
tools.
It contains a byte code verifier named JustIce, which usually gives you
much better information about what is wrong with your code than the
standard JVM message.

- Update to version 6.8.0
* 6.8.0 (2023-12-08) Maintenance and bug fix release.
+ New features:
~ Add and use InvalidMethodSignatureException extending
ClassFormatException.
~ Increase code coverage in Class2HTMLTestCase with new test
input Java4Example #186.
~ Add verifier tests on some opcodes #180.
~ Added signature test cases for class/method, and bad
signatures #182.
~ Add Const.MAJOR_20.
~ Add Const.MINOR_20.
~ Add Const.MAJOR_21.
~ Add Const.MINOR_21.
~ [Bcelifier] stackmap support to pass JDK verifier #177.
~ Fix SpotBugs [ERROR] Class org.apache.bcel.util.ClassVector
defines non-transient non-serializable instance field vec
[org.apache.bcel.util.ClassVector] In ClassVector.java
SE_BAD_FIELD.
~ Fix SpotBugs [ERROR] Switch statement found in
org.apache.bcel.util.BCELFactory.visitAllocationInstruction(AllocationInstruction)
where one case falls through to the next case
[org.apache.bcel.util.BCELFactory,
org.apache.bcel.util.BCELFactory] At
BCELFactory.java:[lines 188-191]Another occurrence at
BCELFactory.java:[lines 192-196] SF_SWITCH_FALLTHROUGH.
+ Fixed bugs:
~ When parsing an class with an invalid constant reference,
ensure ClassParser.parse() throws ClassFormatException, not
NullPointerException.
~ Ensure that references to a constant pool entry with index
zero trigger a ClassFormatException, not a
NullPointerException.
~ Ensure that references to the unused constant pool entry
after a long/double entry triggers a ClassFormatException,
not a NullPointerException.
~ Test and coverage of InstructionFactory #190.
~ Verifier: test and coverage for SWAP instruction #188.
~ Exception parsing Kotlin class with 'fun `method name with
() in it`()' #205.
~ Fix null pointers in AnnotationEntry #213.
~ Field not found, search field in both super class and
implemented interfaces (5x duplicated code to find field by
name and type is refactored to a new method and now
supports package-private) #181.
~ BCEL-366: Use alternative name for broken classes under
test #220.
~ BCEL-367: Fixes java.lang.IndexOutOfBoundsException for
ATHROW on empty stack #223.
~ BCEL-368: Fixes java.lang.StackOverflowError in
Select#toString(boolean) #229.
~ Fix for type.getType(...) use on non-signature type names
#221.
~ Fix EmptyVisitorTestCase on Java 21.
+ Changes:
~ Bump commons-parent from 54 to 65 #189, #198, #222.
~ Bump jna.version from 5.12.1 to 5.13.0 #203.
~ Bump kotlin-stdlib from 1.8.10 to 1.9.21 #217, #219, #227,
#231, #235, #245, #247.
~ Bump commons-io from 2.11.0 to 2.15.1.
~ Bump commons-lang3 from 3.12.0 to 3.14.0.
~ Bump org.codehaus.mojo:exec-maven-plugin from 3.1.0 to
3.1.1 #246.
