Error description
When automatic exception handling is enabled in the decision engine some rules do not execute. An error may be thrown Caused by: java.lang.ClassFormatError: Illegal exception table range in class file com/ibm/rules/generated/ruleflow/task1$003ep1/SEQEngine at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at java.lang.ClassLoader.defineClass(ClassLoader.java:839) at ilog.jit.jvm.IlxJITClassLoader.findClass(IlxJITClassLoader.j ava:133) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) Enabling assertion during ruleset generation (jvm option -ea) an error is thrown used by: java.lang.AssertionError: notAssignableTo boolean_to_string(valueOf(equals_ignore_case(this#expression && this#expression2)), boolean at com.ibm.rules.engine.lang.semantics.util.SemAssertingDiagnos ticHandler.notAssignableTo(SemAssertingDiagnosticHandler.java:5 3) at com.ibm.rules.engine.lang.semantics.SemAbstractCheckedLangua geFactory.adaptToAssignment(SemAbstractCheckedLanguageFactory.j ava:1680) at com.ibm.rules.engine.lang.semantics.SemAbstractCheckedLangua geFactory.checkedVariableAssignment(SemAbstractCheckedLanguageF actory.java:327) at com.ibm.rules.engine.algo.compilation.nullhandling.NullHandl ingStatementBuilder$BooleanVariableStatementBuilder.buildStatem ents(NullHandlingStatementBuilder.java:731) at com.ibm.rules.engine.algo.compilation.nullhandling.NullHandl ingStatementBuilder.buildStatementsWithThrow(NullHandlingStatem entBuilder.java:179) at com.ibm.rules.engine.algo.compilation.nullhandling.NullHandl ingHelper.varDeclBoolWithNullHandling(NullHandlingHelper.java:1 26) at com.ibm.rules.engine.fastpath.compiler.SemSpecializedCompile r.varDeclListWithNullHandling(SemSpecializedCompiler.java:695) at com.ibm.rules.engine.fastpath.compiler.SemSpecializedCompile r.visit(SemSpecializedCompiler.java:391) at com.ibm.rules.engine.fastpath.compiler.SemSequentialCompiler .visit(SemSequentialCompiler.java:1376) at com.ibm.rules.engine.fastpath.compiler.SemStaticSequentialCo mpiler.visit(SemStaticSequentialCompiler.java:340) at com.ibm.rules.engine.fastpath.semantics.SemFromNode.accept(S emFromNode.java:42)
Local fix
Disable Automatic exception handling. or rewrite local definitions using boolean expression so that the expression is evaluated in a boolean local variable before being used in another local variable definition For example: set string1 to get string value when ( var is not null and the length of var is at least 10 ) rewrite as: set test to var is not null and the length of var is at least 10 ; set string1 to get string value when test
Problem summary
**************************************************************** * USERS AFFECTED: * * Decision Engine execution with Automatic Exception Handling * * enabled. * **************************************************************** * PROBLEM DESCRIPTION: * * in some circumstances where a boolean expression is used as * * part of the initial value of a non boolean local variable * * the decision engine may incorrectly evaluate this expression * **************************************************************** * RECOMMENDATION: * ****************************************************************
Problem conclusion
the code is fixed
Temporary fix
