Logging generation processing breaks APT rules by loading classes via reflection -------------------------------------------------------------------------------- Key: LOGTOOL-51 URL: https://issues.jboss.org/browse/LOGTOOL-51 Project: Log Tool Issue Type: Bug Security Level: Public(Everyone can see) Environment: JBDS 5.5.0.CR1 Reporter: Fred Bricon Assignee: David Lloyd Priority: Blocker JBDS 5.5.0.CR1 embeds [m2e-apt|https://github.com/jbosstools/m2e-apt], which automatically enables Eclipse JDT Annotation Processor Toolkit. When importing the [server|https://github.com/jbossas/jboss-as/tree/master/server] module from http://github.com/jbossas/jboss-as.git (also happens for other modules), Eclipse starts crashing (see JBIDE-12087) with errors like : {noformat} javax.xml.parsers.FactoryConfigurationError: Provider __redirected.__DocumentBuilderFactory not found at

So basically, whenever a Logger has a dependency to the [org.jboss.modules.Module|https://github.com/jbossas/jboss-modules/blob/ma...] class, stuff starts hitting the fan. Classes should not be loaded by reflection during APT processing to avoid such issues - it should use the API provided by APT to iterate over the classes metadata provided by the compiler and not depend on com.sun.*.internal classes.
