> The
> [org.apache.bcel.generic.LDC|https://github.com/apache/commons-bcel/blob/master/src/main/java/org/apache/bcel/generic/LDC.java]
> class does not support
> [Const.CONSTANT_Dynamic|https://github.com/apache/commons-bcel/blob/master/src/main/java/org/apache/bcel/Const.java#L683C52-L683C52]
> (Condy, Dynamic class-file constant) in the following methods:
> * {{public Type getType(final ConstantPoolGen cpg);}}
> * {{public Object getValue(final ConstantPoolGen cpg);}}
> JaCoCo >= 0.8.4 (see
> [jacoco/pull/845|https://github.com/jacoco/jacoco/pull/845]) creates class
> files which have Constant_Dynamic. When visiting the instructions of a method
> and calling either of the mentioned method of LDC, an
> IllegalArgumentException occurs: "{{Unknown or invalid constant type at 32}}".
> This error causes a problem, when someone tries to analyze a class file
> containing condy with spotbugs, which uses BCEL. The error was originally
> found in spotbugs (see
> [spotbugs/issues/2503|https://github.com/spotbugs/spotbugs/issues/2503] and
> [spotbugs/pull/2512|https://github.com/spotbugs/spotbugs/pull/2512]).
> Attached a class built by Java 17 and JaCoCo 0.8.9., the source of this file
> is
> [spotbugs/issues/2503/comment|https://github.com/spotbugs/spotbugs/issues/2503#issuecomment-1679085646].
> The issue can be reproduced by calling the
> [org.apache.bcel.generic.TypeTestCase.testLDC(String
> className)|https://github.com/apache/commons-bcel/blob/master/src/test/java/org/apache/bcel/generic/TypeTestCase.java#L71]
> method with the attached class file as a parameter.
