Build Identifier: 2.3.1.v20111018-r10243 After upgrading to EclipseLink 2.3.1, a specific class could not be weaved with a very strange error: ------------------ SNIP --------------------------- gr.auth.meng.isag.aekk.operations.om.Transportation woven gr.auth.meng.isag.aekk.om.AekkInstallation woven gr.auth.meng.isag.aekk.operations.om.MaterialToTransport woven gr.auth.meng.isag.aekk.operations.om.Quantity woven gr.auth.meng.isag.aekk.operations.om.DemolitionOperation woven [EL Warning]: 2011-11-09 00:16:04.864--ServerSession(1548978993)--Thread(Thread[JPA-Activation,5,main])--Weaver encountered an exception while trying to weave class gr.auth.meng.isag.aekk.operations.om.BaseOperation. The exception was: java.lang.RuntimeException: java.lang.ClassNotFoundException: gr.auth.meng.isag.aekk.operations.om.Transportation ------------------ SNIP --------------------------- However, that class was already woven. Digging further into the innards, the class BaseOperations has a method that contains the following code: ------------------ SNIP --------------------------- for (Iterator<Transportation> it = getTransportation().iterator(); it .hasNext();) { Transportation tr = it.next(); if (tr.getMaterials().size() == 0) it.remove(); } ------------------ SNIP --------------------------- Let's rearrange the code a bit: ------------------ SNIP --------------------------- for (Iterator<Transportation> it = getTransportation().iterator(); it .hasNext();) { if (it.next().getMaterials().size() == 0) it.remove(); } ------------------ SNIP --------------------------- The class now weaves without any issue. This bug also occurs in 2.3.0. It looks like the wrong class loader is used in ASM - stack trace follows: Daemon Thread [JPA-Activation] (Suspended (breakpoint at line 65 in ClassNotFoundException))
