searching stackoverflow led me this similar problem

the solution (upgrading java plugin version 3.4) not work since upgraded 3.4. furthermore, rule causing error different, squid:s1643 (strings should not concatenated using '+' in loop):

caused by: java.lang.classcastexception: org.sonar.java.model.expression.parenthesizedtreeimpl cannot cast org.sonar.plugins.java.api.tree.identifiertree @ org.sonar.java.checks.stringconcatenationinloopcheck.getidentifiertree(stringconcatenationinloopcheck.java:98) 

deactivating rule workaround, still use rule. sonarqube version lts (4.5.4).

thanks feedback. unfortunately can't reproduce issue on side based on stack trace. identify , provide simple reproducer of issue? (you should have string concatenation including parentheses somewhere in file causing exception)
