[jboss-jira] [JBoss JIRA] (JBRULES-3537) JIT crash when throwing RuntimeException

JIT crash when throwing RuntimeException ---------------------------------------- Key: JBRULES-3537 URL: https://issues.jboss.org/browse/JBRULES-3537 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.4.0.Final Environment: linux java version "1.7.0_04-icedtea" OpenJDK Runtime Environment (IcedTea7 2.2) (ArchLinux build 7.u4_2.2-1-x86_64) OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode) Reporter: Willem van Asperen Assignee: Mario Fusco There is probably something wrong with my rules. But I get a funny error (see trace below). This seems to be because the ConditionAnalyzer wants to throw a RuntimeException (line 229): if (accessor == null) { throw new RuntimeException("Null accessor on node: " + node); } Then the toString of ASTNode node crashes with a NullPointerException at line 427: public String toString() { return isOperator() ? "<<" + DebugTools.getOperatorName(getOperator()) + ">>" : (PCTX_STORED & fields) != 0 ? nameCache : new String(expr, start, offset); } This is because the variable expr is null.
