Mark Thomas resolved BCEL-129.
------------------------------
Resolution: Fixed
No resposnse to request to re-test against trunk and no test case provided to
enable someone else to test it.
I am therefore going to assume that this was fixed long ago. If that isn;t the
case and you still see this issue on trunk, please feel free to re-open and
provide a test case.

> Hi ,
> I am using BCEL to instrument Java classes of web applications in JDK1.6
> ,1.5 .We encountered a ClassFormat exception for classes using Generics which
> prevented application from loading.From
> https://issues.apache.org/bugzilla/show_bug.cgi?id=33549 I saw a workaround
> to delete "LocalVariableTypeTable". I followed that suggestion and loop
> through the attributes and deleted attribute named "LocalVariableTypeTable".
> Still while loading the application I get a ClassFormatException.
> Example code in which I delete attribute "LocalvariableTypeTable" jc is
> JavaClass Object
> {code}
> Method[] ma = jc.getMethods();
> for(int i = 0, x = ma.length; i < x; i++) {
> try {
> MethodGen mg = new
> MethodGen(ma[i],cg.getClassName(),cg.getConstantPool());
> Attribute[] atts = mg.getCodeAttributes();
>
> for (int j = 0; j < atts.length; j++) {
> if (atts[j].getNameIndex() ==
> mg.getConstantPool().lookupUtf8("LocalVariableTypeTable")) {
> mg.removeCodeAttribute(atts[j]);
> }
> }
> } catch(Exception o1) {
> output.write("exception " + o1);
> }
> }
> {code}
> Also I get other error
> {code}
> Caused by: java.lang.ClassFormatError: LVTT entry for 'patterns' in class
> file org/springframework/classname does not match any LVT entry
> {code}
> and the application fails to load
