Solving exception

[Former user]

Hello,

Solve[{1.0dq4+1.0e == 100,1.0cq3 == 100,1.0aq1 == 100,1.0eq5 == 100,1.0b*q2 == 100}, {a,b,c,d,e}]

returns the following exception:

java.lang.NullPointerException at org.matheclipse.core.eval.EvalEngine.evalObject(EvalEngine.java:873) at org.matheclipse.core.eval.EvalEngine.evalLoop(EvalEngine.java:824) at org.matheclipse.core.eval.EvalEngine.evalWithoutNumericReset(EvalEngine.java:278) at org.matheclipse.core.eval.EvalEngine.evaluate(EvalEngine.java:297) at org.matheclipse.core.eval.EvalEngine.eval(EvalEngine.java:337) at org.matheclipse.core.expression.F.eval(F.java:2859) at org.matheclipse.core.reflection.system.Roots.rootsOfVariable(Roots.java:123) at org.matheclipse.core.reflection.system.Solve.rootsOfUnivariatePolynomial(Solve.java:421) at org.matheclipse.core.reflection.system.Solve.analyzeSublist(Solve.java:330) at org.matheclipse.core.reflection.system.Solve.analyzeSublist(Solve.java:359) at org.matheclipse.core.reflection.system.Solve.analyzeSublist(Solve.java:359) at org.matheclipse.core.reflection.system.Solve.analyzeSublist(Solve.java:359) at org.matheclipse.core.reflection.system.Solve.analyzeSublist(Solve.java:359) at org.matheclipse.core.reflection.system.Solve.evaluate(Solve.java:499) at org.matheclipse.core.eval.EvalEngine.evalASTBuiltinFunction(EvalEngine.java:644) at org.matheclipse.core.eval.EvalEngine.evalAST(EvalEngine.java:560) at org.matheclipse.core.eval.EvalEngine.evalObject(EvalEngine.java:874) at org.matheclipse.core.eval.EvalEngine.evalLoop(EvalEngine.java:837) at org.matheclipse.core.eval.EvalEngine.evalWithoutNumericReset(EvalEngine.java:278) at org.matheclipse.core.eval.EvalEngine.evaluate(EvalEngine.java:297) at org.matheclipse.core.eval.EvalUtilities.evaluate(EvalUtilities.java:45)
