Summary

0003598: javax.el.ELException: java.lang.IllegalAccessException

Description

in BeanELResolver.java

code
if (descriptor.getReadMethod() != null)
descriptor.getReadMethod().setAccessible(true);

behaves not as expected because PropertyDescriptor stores SoftReference
after some GC JVM cleans SoftReferences and we loose .setAccessible(true) setting.

Additional Information

This means, we can't use JSTL on Resin 4.0.0, as after a while application throws

javax.el.ELException: java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class java.util.HashMap$Entry with modifiers "public final" at javax.el.BeanELResolver.getValue(BeanELResolver.java:201) at com.caucho.jsp.el.PageContextELResolver.getValue(PageContextELResolver.java:181) at com.caucho.el.ArrayResolverExpr.getValue(ArrayResolverExpr.java:148) at com.caucho.el.PathExpr.getValue(PathExpr.java:142) at com.caucho.el.Expr.evalString(Expr.java:276) at com.caucho.el.Marshall$8.marshall(Marshall.java:116) at com.caucho.el.StaticMethodExpr.evalMethod(StaticMethodExpr.java:128) at com.caucho.el.FunctionExpr.getValue(FunctionExpr.java:69) at com.caucho.el.Expr.print(Expr.java:416) at jsp._WEB_22dINF._tags._common._pageIndextag.doTag(_pageIndextag.java:131) at _jsp._WEB_22dINF._jsp._company._searchResultsjsp._jspService(_searchResultsjsp.java:288) at

Resin 3.2.1 was not affected because it also stored hard reference to the readMethod (in the same BeanELResolver.java)

private void initDescriptor()
    {
      Method readMethod = _descriptor.getReadMethod();

      if (readMethod != null)
    _descriptor.setValue(ELResolver.TYPE, readMethod);
