Classfile API allowed to generate Code attribute exceeding the 65k limit. No exception has been thrown during class generation and the class failed verification later during class loading. This patch adds Code size limit check throwing IllegalArgumentException. The patch also adds similar check for constant pool size limit to avoid generation class file with corrupted constant pool. Two new tests are added to check response on oversized Code attribute and constant pool. `VerifierImpl` is extended to check Code attribute size as a part of class verification process.
Please review.
