[jboss-as7-dev] IronJacamar jars causing java.util.zip.ZipException: invalid entry compressed size (expected X but got Y bytes)

Hi all, when I use various tools to manipulate AS jars, this happens with IronJacamar jars: Caused by: java.util.zip.ZipException: invalid entry compressed size (expected 576 but got 577 bytes) at java.util.zip.ZipOutputStream.closeEntry(ZipOutputStream.java:206) at com.vladium.emma.instr.InstrProcessorST.writeZipEntry(InstrProcessorST.java:838) at com.vladium.emma.instr.InstrProcessorST $EntryWriteJob.run(InstrProcessorST.java:905) at com.vladium.emma.instr.InstrProcessorST.drainJobQueue(InstrProcessorST.java:943) at com.vladium.emma.instr.InstrProcessorST.handleArchiveEnd(InstrProcessorST.java:353) ... 5 more How are they packaged? Some special buggy tool? It prevents me from preparing coverage reports, both Emma and JaCoco are affected. Thanks, Ondra
