             Summary: ClassParser fails to parse JDK classes in Java 8: ClassFormatException: Invalid byte tag in constant pool
                 Key: BCEL-173
                 URL: https://issues.apache.org/jira/browse/BCEL-173

          Issue Type: Bug
    Affects Versions: 5.0, 5.1, 5.2

See attached sample project that reproduces the failure.  On Java 7, it prints info about the ConcurrentMap class.  On Java 8, it encounters the following exception:

{code}
Exception in thread "main" org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 18
	at org.apache.bcel.classfile.Constant.readConstant(Constant.java:146)
	at org.apache.bcel.classfile.ConstantPool.<init>(ConstantPool.java:67)
	at org.apache.bcel.classfile.ClassParser.readConstantPool(ClassParser.java:222)
	at org.apache.bcel.classfile.ClassParser.parse(ClassParser.java:136)
	at TestMain.main(TestMain.java:11)
{code}

To use the sample project, extract it and then run "./gradlew clean run".
